When the great ice sheet of the last glaciation withdrew from northern Europe, some 12,000 years ago, the first hunters followed the reindeer and the large animals into the lands that are Denmark today. Those Stone Age peoples lived from hunting, fishing and gathering along an extremely rich coast; the enormous shell mounds —the kjøkkenmøddinger or "kitchen middens"— that they left beside the fjords are among the first ever studied scientifically anywhere in the world, and they even gave the phenomenon its name. In time farming arrived, and with it the great megalithic tombs, the stone dolmens that still dot the Danish countryside by the thousand.
The Nordic Bronze Age (around 1700-500 BC) was a period of surprising splendour. With no metal deposits of their own, Danish communities traded Baltic amber for the bronze that came from the south, and cast from it objects of astonishing beauty: the Trundholm Sun Chariot, a horse pulling a gilded disc, or the great lurs, curved bronze trumpets. In peat bogs and marshes they placed offerings to their gods, in a religion tied to the sun and to fertility.
The most striking finds come from the Iron Age: the "bog men". The body of Tollund Man, found in 1950 in a Jutland peat bog, was so perfectly preserved after more than two thousand years —skin, stubble and a serene expression intact— that those who found him believed they had come across the victim of a recent crime. He died by hanging, probably in a ritual sacrifice. Alongside him, Grauballe Man and other bodies offer a unique, almost tactile window onto pre-Roman Denmark. From those warrior societies of the north, which left an enigma of gods and rites on the great silver cauldron of Gundestrup, would come centuries later the peoples who would astonish Europe.
At the end of the 8th century, Viking raids shook Europe, and the Danes were among their most formidable protagonists. In their long, light, shallow-draught ships, able to cross open sea and push up rivers, they sacked monasteries and cities, laid siege to Paris and spread terror from Ireland to the Mediterranean. But reducing the Vikings to raiders is a historical mistake: they were, in equal measure, traders dealing in furs, slaves, amber and silver along routes that reached Baghdad, and above all settlers who put down roots in new lands. In Denmark they built trading towns such as Hedeby and Ribe, and circular fortresses of geometric precision —the Trelleborg ring forts— that reveal an increasingly organised royal power.
Their deepest mark was left in England. In 865 the "Great Heathen Army", largely Danish, invaded the Anglo-Saxon kingdoms and conquered vast territories in the north and east of the island, the region that would become known as the Danelaw, where Danish law and language ruled for generations and whose place names ending in -by or -thorpe still betray that Scandinavian origin. Not even Alfred the Great of Wessex managed to drive them out entirely.
The high point came with Cnut the Great. Son of the Danish king Sweyn Forkbeard, Cnut conquered England and had himself crowned there in 1016; soon after he inherited Denmark and subdued Norway, forging a "North Sea Empire" that, for around two decades, united the three crowns under his sceptre. Cnut ruled England as a Christian and respected king —he is the source of the famous legend of the monarch who orders the waves to stop in order to show his courtiers the limits of human power. That empire fell apart after his death in 1035, but it left behind the idea of a Denmark capable of projecting itself across the sea and of dealing as an equal with the powers of Europe.
In the heart of Jutland, in the village of Jelling, stand two great burial mounds and two runestones that are Denmark's founding monument. The smaller stone was raised by King Gorm the Old in memory of his wife Thyra; the larger one, a granite block almost three metres high carved with the figure of Christ, was commissioned around the year 965 by his son Harald "Blåtand" —Bluetooth. Its runic inscription declares that Harald "won for himself all Denmark and Norway and made the Danes Christian". Because it brings together in a single sentence the name of the country, the unification of the kingdom and the conversion, the Jelling stone is known as "Denmark's baptismal certificate", and the site is a Unesco World Heritage Site.
Christianisation was a political process as much as a spiritual one. Adopting the faith of Rome moved Denmark away from the threat of conquest by the Germanic Empire, which justified its wars as crusades against pagans, and gave the kings an organised Church, a written language and an ideology of power. The missionary Ansgar, "apostle of the North", had already preached in Hedeby and Ribe in the 9th century, but it was under Harald that Christianity was established as the kingdom's official religion.
A thousand years later, Harald Bluetooth left an unexpected mark: Bluetooth technology carries his name, and its symbol combines the runes of his initials, in tribute to a king who "united" peoples the way the standard unites devices. His son Sweyn and his grandson Cnut would take Danish power to its peak over England. With Christianisation, Denmark entered medieval Europe in full: stone churches were built, bishoprics were founded, and a monarchy backed by the Church began to consolidate its authority over the old chieftains.
After the ebb of Cnut's empire, the Danish High Middle Ages were a time of dynastic civil wars, until in the 12th century the kingdom recovered strength and ambition under the Valdemar dynasty. King Valdemar I the Great (1157-1182) and his son Valdemar II the Victorious (1202-1241) took Denmark to a new peak, with the inseparable help of an exceptional figure: Bishop Absalon, adviser, warrior and statesman, who fought the Slavic pirates of the Baltic, fortified a fishing village that would become Copenhagen and sponsored the first great chronicle of Danish history, the Gesta Danorum of Saxo Grammaticus.
Denmark then launched into expansion across the southern Baltic, subduing the Wendish peoples and taking part in the northern crusades. According to legend, during a battle in Estonia in 1219 a red flag with a white cross fell from the sky and gave the Danes victory: the Dannebrog, regarded as the oldest national flag in continuous use in the world. At its height, the kingdom controlled territories on the Baltic coast and in northern Germany.
That power had its ups and downs. The defeat and captivity of Valdemar II plunged Denmark into chaos for a time, and by the early 14th century the kingdom was so deep in debt that the king pawned whole portions of the country to German nobles and counts. Recovery came with Valdemar IV Atterdag (1340-1375), who through cunning and war reunified the kingdom, recovered the pawned territories and restored the crown's authority, preparing the ground —through his daughter Margrete— for the greatest political construction of medieval Scandinavia.
The most remarkable political figure of medieval Scandinavia was a woman: Margrete I of Denmark. Daughter of Valdemar IV, married to the king of Norway, she was left a widow with no surviving direct heir, but with exceptional diplomatic skill and determination she gathered in her hands the crowns of Denmark, Norway and Sweden. In 1397, in the Swedish town of Kalmar, she sealed the union of the three Scandinavian kingdoms under a single monarch —her great-nephew Eric of Pomerania, whom she had crowned— although real power stayed in Margrete's hands until her death in 1412. So was born the Kalmar Union, the largest political entity in the history of northern Europe.
The union brought together millions of people and an immense territory, from the North Cape to the German duchies, with Denmark as the dominant partner. But it was a fragile construction from the start. Sweden, with a powerful nobility jealous of its autonomy, resisted Danish dominance again and again, and the union lived among rebellions, truces and reconciliations for more than a century.
The final blow came in 1520, with the so-called "Stockholm Bloodbath": the Danish king Christian II, after entering the Swedish capital, executed dozens of Swedish nobles and prelates accused of heresy and treason. The massacre triggered a general uprising led by the young nobleman Gustav Vasa, who in 1523 was crowned king of an independent Sweden. The Kalmar Union broke apart for good; Norway, on the other hand, would remain tied to Denmark for another three centuries. The rupture opened centuries of rivalry and war between Copenhagen and Stockholm over control of the Baltic and of Scandinavia.
As in the rest of northern Europe, the Protestant Reformation transformed Denmark from the roots up. Luther's ideas, arriving from neighbouring Germany, caught on strongly among the burghers and part of the nobility, while the Catholic Church, owner of enormous wealth, was viewed with growing hostility. The religious question became entangled with a brutal civil war over the throne: the "Grevens Fejde", the Count's Feud (1534-1536), the country's last great internal conflict, which pitted the supporters of the deposed Christian II and of the towns against the landowning nobility.
The winner was Christian III, a committed Lutheran. After prevailing militarily, in 1536 he took the decisive step: he had the Catholic bishops arrested, confiscated the Church's immense properties —which passed to the crown, multiplying its power— and established a Lutheran state Church with the king at its head. Denmark became officially Protestant almost overnight, by decision from above rather than through a popular movement.
The consequences were lasting. The confiscation of Church lands made the monarch the largest landowner in the kingdom and weakened the old nobility; the Bible and worship switched to Danish, which boosted the vernacular language; and the Lutheran Church remained a pillar of the state that would shape the country's religious, educational and moral life for centuries. Even today the Church of Denmark, Lutheran, is the national church, and a very large majority of Danes are nominally members of it, a direct inheritance from that year of 1536.
No monarch has left as visible a mark on Denmark as Christian IV (1588-1648), the longest-reigning king in its history. Energetic, ambitious and passionate about architecture, he turned Copenhagen into a capital worthy of a European power: he ordered the building of the Stock Exchange (Børsen) with its spire of intertwined dragons, the Rosenborg pleasure castle, the Round Tower (Rundetårn) with its spiral ramp, entire new districts, shipyards and fortifications. He founded towns such as Christianshavn and Kristiansand, and promoted trade and the colonial companies. His silhouette with the pigtail and the earring is fixed in the national memory as that of a vital, approachable king.
But his reign was also one of great military disasters. Hungry for glory and eager to contain Sweden, Christian IV took Denmark into the Thirty Years' War (1625-1629) on the Protestant side, and suffered a humiliating defeat that brought imperial armies into Jutland. Worse still was the long struggle with a rising Sweden: in the Torstenson War, the Treaty of Brömsebro (1645) forced Denmark to cede the islands of Gotland and Øsel and provinces such as Halland and Jämtland.
The disaster peaked under his son Frederik III. In 1657-1658, the Swedish king Charles X Gustav took advantage of an exceptionally cold winter that froze the Danish straits and marched his army across the ice from Jutland to the islands, a daring move that left Copenhagen at Sweden's mercy. The Treaty of Roskilde of 1658 was the harshest in Danish history: Denmark ceded for ever Scania (Skåne), Halland and Blekinge, the fertile and populous eastern half of the kingdom, which today forms the south of Sweden. At a stroke, Denmark lost close to a third of its territory and its population, and the Øresund strait stopped being an internal Danish waterway and became a border. The defeat sealed the end of Denmark as a great Baltic power.
The humiliation at Sweden's hands had an unexpected political consequence. In 1660, with the country ruined and the old nobility discredited by defeat, King Frederik III summoned an assembly of the estates in Copenhagen. With the backing of the clergy and the capital's burghers —and of the garrison— he carried out a genuine coup against the aristocracy: he abolished the elective monarchy, made the crown hereditary and concentrated all power in the king. In 1665 the Kongeloven, or "King's Law", formalised the regime: one of the most radical absolutist texts in Europe, declaring the monarch answerable to God alone. Denmark would be an absolute monarchy for almost two centuries, until 1848.
Absolutism, paradoxically, made it possible to modernise the administration and, in time, to undertake enlightened reforms. The most famous episode was that of the German doctor Johann Friedrich Struensee, who in the early 1770s became the kingdom's strongman during the mental illness of King Christian VII. In barely sixteen months of near total power, Struensee decreed on his own authority a torrent of radical reforms —freedom of the press, abolition of torture, cuts to privileges— while also carrying on an affair with Queen Caroline Matilda. The court's reaction was swift: he was overthrown, tried and executed in 1772.
Towards the end of the century, however, more lasting reforms arrived. The great agrarian reforms of the 1780s and 1790s abolished the serfdom that bound peasants to the land (the stavnsbånd) and encouraged the creation of a class of landowning farmers, laying the foundations of modern rural Denmark. In 1792, moreover, Denmark was one of the first countries in the world to ban the Atlantic slave trade to its colonies, although the trade did not stop immediately and slavery persisted in the Danish West Indies until 1848. The country entered the 19th century as an absolute but reforming monarchy, prosperous thanks to its neutral maritime trade.
The prosperous neutral trade that Denmark carried on at the height of the Napoleonic wars put it in the sights of Great Britain, master of the seas. In 1801, a British fleet under Nelson attacked Copenhagen itself in a bloody naval battle to force Denmark out of the League of Armed Neutrality. But the worst came in 1807: fearing that the powerful Danish fleet would fall into Napoleon's hands, the British demanded it be handed over and, when Denmark refused, bombarded Copenhagen for three nights. The attack —one of the first deliberate bombardments of a civilian population in the modern era— set entire districts on fire, killed hundreds of civilians and ended with the capture of the whole Danish fleet.
The bombardment pushed Denmark into Napoleon's arms, which turned out to be the wrong alliance. When the French emperor fell, the victors made Denmark pay for its loyalty: under the Treaty of Kiel, in January 1814, King Frederik VI had to cede Norway to the king of Sweden. So ended more than four centuries of Danish-Norwegian union. Denmark kept the old Norwegian Atlantic dependencies —Iceland, the Faroes and Greenland— but lost an entire kingdom.
The blow was enormous. Reduced to Jutland, the islands and the German duchies to the south, ruined by the war —the state went bankrupt in 1813— Denmark left behind its dreams of great power status for good. And yet, out of that smallness and that retreat would come, in the following decades, a remarkable cultural flowering: the country turned inward the energies it could no longer project outward, and lived its Golden Age.
The first half of the 19th century was, despite the material ruin, the "Guldalder", the Golden Age of Danish culture. In an impoverished but intense Copenhagen, talents flourished that would give Denmark a universal place. Hans Christian Andersen raised the folk tale to the level of art with stories such as The Ugly Duckling, The Little Mermaid and The Emperor's New Clothes, translated into almost every language in the world. The philosopher Søren Kierkegaard, regarded as the father of existentialism, wrote in Danish a body of work that questioned anguish, faith and individual freedom. The sculptor Bertel Thorvaldsen achieved European fame with his neoclassicism, and the physicist Hans Christian Ørsted discovered electromagnetism in 1820, opening a new era in science.
To that cultural ferment was added a political and social one. The pastor, poet and educator N.F.S. Grundtvig inspired the folk high school movement (folkehøjskoler), a form of adult education tied to the farming community that would prove decisive for democratic Denmark, and helped forge a strong national feeling. At the same time, the cooperative movement transformed the countryside, organising small farmers into shared dairies and slaughterhouses that made Denmark an agricultural export power.
Liberal pressure came to a head in 1848-1849. In the revolutionary climate shaking all of Europe, King Frederik VII accepted the end of absolutism without resistance. On 5 June 1849 the "Grundlov", the first Danish Constitution, was promulgated, turning the country into a constitutional monarchy with an elected parliament (the Rigsdag) and guaranteed freedoms. It was one of the most peaceful transitions in the Europe of the day, and 5 June is still Constitution Day, a Danish national holiday. That charter opened a long and bumpy road towards democracy.
The most painful episode of 19th-century Denmark was the question of the duchies. South of Jutland, the duchies of Schleswig and Holstein, tied to the Danish crown but with a mixed population —Danish in the north, German in the south— became the focus of an explosive nationalist conflict in the age of German unification. A first war, the First Schleswig War (1848-1851), pitted Denmark against the German rebels of the duchies and ended in a Danish victory that resolved nothing fundamental.
The outcome came in 1864. When Denmark tried to integrate Schleswig more closely, Bismarck's Prussia, allied with Austria, declared war. It was an unequal and short conflict. In April 1864, after weeks of siege, Prussian troops stormed the Danish trenches at Dybbøl, near Sønderborg, in a battle that became a symbol of national sacrifice and defeat. Denmark, isolated and without allies, had to cede Schleswig, Holstein and Lauenburg. It lost close to 40% of its territory and some 200,000 Danes in northern Schleswig were left under German rule.
The defeat of 1864 was a trauma that reoriented the country's identity. Reduced to the smallest core in its history, Denmark abandoned any ambition of great power status for good and turned in on itself. From that moment came the famous motto attributed to the engineer Enrico Mylius Dalgas —"what is lost without will be won within"— which inspired the colossal effort to cultivate and afforest the barren heaths of Jutland and to pour national energy into internal progress. A small, agricultural, cooperative and educated Denmark began to be built on the ashes of defeat.
The turn from the 19th to the 20th century was, in Denmark, the consolidation of democracy. In 1901 the principle of parliamentarism —the "Systemskifte"— was established, whereby the government had to have the backing of a parliamentary majority and not just the king's confidence, ending decades of tug-of-war between the conservative crown and the liberal chamber. The constitutional reform of 1915 widened the right to vote and at last included women's suffrage, putting Denmark among the first countries in the world to recognise it. Mass parties —agrarian liberals, conservatives and, with growing strength, the Social Democrats— gave shape to a stable political life.
During the First World War (1914-1918), Denmark managed to stay neutral, like Sweden and Norway, though it had to manoeuvre with extreme caution between the great powers and suffered economic hardship and the loss of sailors to submarine warfare. Neutrality spared it the catastrophe that devastated the continent.
The end of the war also brought a historic redress. Germany's defeat made it possible to reopen the question of the Schleswig lost in 1864. In 1920, following the post-war principles of self-determination, plebiscites were held in the region: the northern zone, with a Danish majority, voted to rejoin Denmark, while the central and southern zone, with a German majority, chose to stay in Germany. On 10 July 1920, King Christian X rode across the old border on horseback to take possession of the reincorporated North Schleswig: the "Genforening", or Reunification, one of the most celebrated days in modern Danish history, which fixed the German-Danish border still in place today, now regarded as a model of coexistence between minorities.
On 9 April 1940, Nazi Germany invaded Denmark. The country, small, flat and practically indefensible, capitulated within hours after a symbolic resistance that cost about a dozen lives. Unlike other occupied territories, Denmark at first kept a peculiar autonomy: the government, the parliament and the king carried on under a "policy of cooperation" with the occupier, which Berlin tolerated in order to present the country as a "model protectorate" and to secure its agricultural output. That collaboration, which avoided the worst for three years, is still the subject of a legitimate historical debate about its moral limits.
As the war went on, resistance grew: sabotage, an underground press, strikes. In August 1943, faced with the government's refusal to impose the death penalty for saboteurs, the Germans broke the agreement, dissolved the Danish government and imposed a state of emergency. It was then that the decisive hour came for Denmark's roughly 7,000 Jews.
In September 1943, a German diplomat, Georg Ferdinand Duckwitz, secretly leaked the date of the deportation planned for the beginning of October. The warning spread by word of mouth through the resistance, the Church and ordinary citizens. In just a few weeks, a spontaneous network of fishermen, doctors, priests and neighbours hid the Jewish families and shipped them out by night, across the Øresund strait, to neutral Sweden. More than 7,000 Jews and several hundred of their non-Jewish relatives were brought to safety. Of those who did not manage to flee, some 470 were deported to the Theresienstadt camp; thanks to insistent pressure from the Danish government and Red Cross, the vast majority survived. In all, more than 99% of Danish Jews came through alive, a case that is almost unique in occupied Europe. The rescue does not erase the grey areas of collaboration, but it remains one of the brightest episodes of those dark years. Denmark was liberated on 5 May 1945.
The post-war years transformed Denmark. Abandoning its old neutrality, it was one of the founding countries of NATO in 1949, aligning itself with the West in the Cold War. At home, Social Democrat governments, often in agreement with the other parties, built between the 1950s and the 1970s one of the most advanced welfare states in the world: free healthcare and education, universal pensions and benefits, childcare, and a model —known as "flexicurity"— that combines a flexible labour market with strong social protection. Funded by high taxes and sustained by a remarkable social consensus and great trust in institutions, that model made Denmark one of the most equal, prosperous and, according to surveys, happiest societies on the planet.
In its relationship with Europe, Denmark chose integration with reservations. In 1973 it joined the European Economic Community, along with the United Kingdom and Ireland, breaking with its traditional continental distance. But it kept a cautious relationship: in 1992 Danes rejected the Maastricht Treaty in a referendum, and only approved it the following year after obtaining four opt-outs, among them not adopting the euro. Denmark thus keeps its own currency, the krone, and has stayed outside parts of European integration.
The kingdom still includes two autonomous North Atlantic territories: the Faroe Islands, self-governing since 1948, and Greenland, the largest island in the world, autonomous since 1979 and with broad self-government since 2009 that allows for possible future independence; Greenland in fact left the European Community in 1985. On the symbolic level, the long era of Queen Margrethe II —on the throne since 1972— closed with a gesture unheard of in the Danish monarchy: her abdication on 14 January 2024 in favour of her son, crowned as Frederik X. Stable, prosperous and deeply rooted in its thousand-year history, the Denmark of the 21st century remains one of the oldest monarchies in the world and, at the same time, one of its most admired social laboratories.
The 4 histories, one after another. Use the buttons above to jump to the one you want.
Bornholm is an anomaly within Denmark. Set in the middle of the Baltic Sea, far to the east of the rest of the country —closer to Sweden, Germany and Poland than to Copenhagen— it is a remote island with a character of its own. It is also geologically different: while the rest of Denmark is a flat country of sand, clay and glacial deposits, Bornholm is an island of hard rock, of granite and other ancient rocks of the Scandinavian basement that surface here, giving it cliffs, hills and a rocky coast unlike anywhere else in the country.
That geology shaped its history and its economy. Bornholm stone was quarried from granite for centuries, and the clay in its soil fed a tradition of ceramics and clockmaking for which the island was famous. The climate, moreover, is one of the sunniest in Denmark, which earned it the nickname "solskinsøen", the "sunshine island", and a vegetation with fig and mulberry trees that is surprising at these latitudes.
Its strategic position in the middle of the Baltic made Bornholm, over the centuries, a coveted and disputed prize. During the Middle Ages it was for a long time under the rule of the archbishop of Lund and, later, of the Hanseatic city of Lübeck, before returning fully to the Danish crown. Isolated, rocky and sunny, Bornholm developed a strong island identity that can still be felt today in its landscape, its dialect and its way of life.
Bornholm's most distinctive monument is its round churches (rundkirker), a type of medieval church of which the island preserves four —Østerlars, Nylars, Nyker and Olsker— the best examples in Scandinavia. Built in the 12th century, in whitewashed stone and with conical roofs, they were not only places of worship: they were also fortresses and refuges. Their thick circular walls, their narrow loopholes and their crenellated upper floor served to protect the population and their belongings from the attacks that plagued the medieval Baltic.
Those attacks were a constant threat. First the Slavic (Wendish) pirates, and later raids and wars, made life on an exposed Baltic island a permanent risk. The round churches, with their double function of church and bastion, are stone witnesses to that insecurity: in times of danger, farmers crowded in with their families, their livestock and their supplies on the upper floor, turned into a stronghold.
The largest and most impressive is Østerlars, with a massive hollow central pillar decorated with medieval frescoes. These churches, unique in their shape and their age, are today one of Bornholm's great attractions and a symbol of its history of isolation and danger. They are still in use as parish churches, a thousand years after being raised to pray and to resist.
At the northwestern tip of Bornholm, on a granite crag dropping to the sea, stand the ruins of Hammershus, the largest medieval fortress in northern Europe. Begun probably in the 13th century by the powerful archbishop of Lund, who disputed the island with the Danish crown, it dominated Bornholm for centuries and was the scene of the struggles for control of the island between the archbishops, the Danish kings and the Hanseatic city of Lübeck, which occupied Bornholm for long decades.
Hammershus was far more than a castle: it was an impregnable citadel, with a vast walled enclosure, towers, churches and outbuildings, protected by cliffs and by its commanding position over the Baltic. It served as a residence, a garrison and also a state prison; within its walls was shut away, for example, the unfortunate Leonora Christina, daughter of King Christian IV, during the intrigues of the 17th century.
With the arrival of modern artillery and the end of the wars that justified its existence, the fortress lost its usefulness and in the 18th century it was abandoned; for years it was even used as a stone quarry for buildings on the island. Finally saved as a national monument, its imposing ruins, battered by the Baltic wind, are today the great testimony to Bornholm's turbulent past and one of the most impressive places in Denmark.
The most heroic episode in Bornholm's history took place in 1658. Under the Treaty of Roskilde of that year, which closed a disastrous war with Sweden, Denmark had to cede many territories, among them the island of Bornholm, which passed into Swedish hands. But the people of Bornholm did not accept the change of sovereignty. The new Swedish governor, Colonel Printzensköld, set about forcibly recruiting the islanders into the Swedish army, which sparked the revolt.
In December 1658, a group of conspirators led by Jens Kofoed and the priest Poul Anker organised an uprising. They ambushed governor Printzensköld in Rønne and killed him, took control of the island, expelled the Swedish garrison and proclaimed Bornholm's return to the Danish crown. It was a successful popular insurrection, an unusual thing in the Europe of the time.
The rebels then took a symbolic and decisive step: they handed the island over as a "gift" to King Frederik III of Denmark, on the condition that Bornholm should never again be ceded or pawned to a foreign power. The king accepted, and the promise has held: unlike Scania and the other provinces lost in 1658, Bornholm returned to Denmark and has been Danish ever since. The revolt of 1658 is the founding feat of Bornholm's identity, still celebrated as the moment when the island decided its own fate.
The end of the Second World War left Bornholm with a singular wound, different from that of the rest of Denmark. While the country was liberated on 5 May 1945 and the German occupation ended peacefully, on Bornholm the German garrison commander refused to surrender to the Soviets advancing across the Baltic, and would only capitulate to the Western allies. The Soviet Union's response was forceful.
On 7 and 8 May 1945 —when the war was already ending in the rest of Europe— Soviet aircraft bombed the island's two main towns, Rønne and Nexø, to force the German surrender. The attacks killed civilians and destroyed hundreds of buildings in both places, which had to be rebuilt afterwards with Swedish help. It was one of the few places in Denmark that suffered mass destruction in the war, and precisely in its final hours.
After the German surrender, Soviet troops landed and occupied Bornholm. The occupation lasted almost a year, until April 1946, when the Red Army withdrew and the island returned to Danish administration. In the early days of the Cold War, the brief Soviet occupation of Danish territory was a delicate episode and one long remembered on the island. The memory of those last-minute bombings and of the occupation that followed is still a central part of Bornholm's identity.
Bornholm's traditional economy revolved for centuries around the sea, and very particularly around herring. The Baltic shoals sustained a large fishing industry and, above all, a tradition of smokehouses —the "røgerier", recognisable by their tall white chimneys— where herring was smoked over alder wood. "Sun over Bornholm", smoked herring served with a raw egg yolk, onion and radish, became the island's emblematic dish and is still its culinary signature.
Alongside fishing came the industries born of the island's rock and clay: the granite quarries, ceramics and the famous Bornholm clockmaking of the 18th and 19th centuries. That tradition of handwork led, in modern times, to a vibrant scene of craftspeople —glassblowers, ceramicists, silversmiths— who have made Bornholm one of the great centres of applied arts in Scandinavia, with workshops and galleries spread across the island.
In recent decades, that crossing of sea, land and craft has turned Bornholm into a fashionable destination for its food and its quality of life. The island has won fame for its restaurants, its artisan products, its converted smokehouses and a cuisine that makes the most of local ingredients; it has even earned culinary distinctions that are remarkable for such a small and remote place. From smoked herring to fine dining, from granite quarries to art galleries, Bornholm has managed to reinvent its old culture of handwork without losing its identity as a remote island in the heart of the Baltic.
Wedged between Jutland and Zealand, the island of Funen (Fyn) is the third largest in Denmark and occupies the country's geographical centre, a natural bridge between the mainland peninsula and the eastern islands. Its fertile soil, its mild climate, its rolling fields dotted with farms, hedges and orchards, and its abundance of manor houses and castles earned it the affectionate nickname of "the garden of Denmark". This is a Funen of gentle, rural landscape, very different from the harshness of the Jutland coasts.
Its central position made Funen a crossroads from early on. Through it ran the route linking the two halves of the kingdom, and controlling its straits —the Little Belt to the west, the Great Belt to the east— meant controlling Denmark's internal communications. That strategic importance explains why royal strongholds, castles and significant towns clustered on Funen throughout the Middle Ages.
For centuries, however, crossing the straits around the island was slow and dangerous, dependent on ferries at the mercy of the weather. The great transformation came at the end of the 20th century with two colossal feats of engineering: the Great Belt fixed link, opened in 1997-1998 —with one of the longest suspension bridges in the world and an underwater rail tunnel— which at last joined Funen to Zealand and Copenhagen, and the Little Belt link towards Jutland. Funen stopped being a compulsory crossing by boat and became a fixed link in Denmark's backbone.
The capital of Funen, Odense, is one of the oldest cities in Denmark; its name means "Odin's sanctuary", after the supreme god of Norse mythology, and betrays its origin as a place of pagan worship predating Christianisation. It is mentioned in documents as early as the year 988, and it was an important religious and political centre throughout the Middle Ages.
The episode that marked its history took place in 1086. King Canute IV, determined to strengthen the monarchy and the Church, to impose taxes and even to claim the throne of England, provoked a rebellion of peasants and nobles. Pursued, he took refuge in Saint Alban's church in Odense, where he was killed before the altar along with his brother and his followers. Miracles were soon attributed to him, and in 1101 he was canonised: Canute became Saint Canute (Knud den Hellige), the first Danish saint and patron of the kingdom.
Over his tomb rose the imposing Saint Canute's Cathedral, one of the country's masterpieces of brick Gothic, in whose crypt the remains of the martyr king are still kept. Canute's sanctity tied Odense to the Church and to the monarchy for centuries, and the city grew as an episcopal seat and a royal stronghold. That medieval past lives today alongside the lively atmosphere of a university city, the country's third largest.
To the whole world, Odense is the city of Hans Christian Andersen. The most universal of Danish writers was born here in 1805, into a desperately poor family: his father was a cobbler and his mother a washerwoman. That childhood of hardship, in the alleys of early 19th-century Odense, would leave a deep mark on his tales, peopled with poor children, despised ducklings and little match girls. At fourteen, the young Andersen left his home town for Copenhagen to seek his fortune in the theatre.
Andersen ended up as one of the great authors of world literature. His fairy tales —The Little Mermaid, The Ugly Duckling, The Emperor's New Clothes, The Snow Queen, The Little Match Girl— have been translated into more than a hundred languages and are read all over the planet, to the point that his name is a synonym for the genre. His work combines tenderness, social irony and a very personal melancholy, and it raised the folk tale to the level of great literature.
His home town has turned his memory into central heritage. The district where he grew up preserves period houses, and Odense has a modern and much-praised museum dedicated to the writer —the H.C. Andersens Hus— opened in its current form in 2021, which recreates the universe of his tales. Every summer, the city fills with festivals, parades and performances inspired by his stories. Walking through Odense means, to a large extent, walking through the childhood setting of the man who taught several generations of children around the world to dream.
Though today it is a quiet town on the shore of the Great Belt, Nyborg was for much of the Middle Ages the political centre of Denmark. Its castle, built around 1170 to watch over the strait, became a royal residence and the seat of the Danehof, the assembly of the kingdom where the king, the nobles and the prelates met. Sitting at the country's midpoint, on the route linking Jutland with Zealand, Nyborg was the natural place from which to govern a Denmark split between the peninsula and the islands.
In that castle was signed, in 1282, a document of the first importance: the "håndfæstning", or charter, that King Eric V Klipping had to grant the nobility, undertaking to convene the Danehof every year and to govern according to law rather than his own will. It is regarded as Denmark's first constitutional charter, a medieval precedent for limiting royal power, in the same European line as the English Magna Carta. For almost two centuries, Nyborg worked as a de facto capital of the kingdom.
In time the court moved to Copenhagen and Nyborg lost its primacy, but it kept its role as a stronghold guarding the Great Belt crossing, and it suffered sieges and battles in the wars with Sweden. Today its restored castle, one of the oldest in northern Europe, and its historic centre recall the era when this small Funen town was the political heart of Denmark.
In the south of Funen stands one of the best-preserved moated castles in Europe: Egeskov. It was built in 1554 by the nobleman Frands Brockenhus, in the middle of the civil and religious wars that followed the Reformation, and for that reason it was raised as a genuine defensive fortress. Its setting is astonishing: it is built in the middle of a small lake, on thousands of oak piles driven into the bottom, so that the water itself served as moat and defence. Its name, Egeskov, means precisely "oak forest", in reference to the timber used in its foundations.
The castle, with its two towers joined by a wall and its red-brick walls reflected in the water, is a jewel of the Danish Renaissance. It was designed to withstand sieges in turbulent times: its thick walls, its gun loops and its single access by drawbridge made it almost impregnable. Legend says it took the timber of a whole oak forest to hold it up above the lake.
Egeskov survives today in exceptional condition and remains in the hands of a noble family, but it opens its doors to the public. Beside the castle spread famous historic gardens, with mazes of century-old hedges, and various collections —of vintage cars and motorcycles, among others— that make the visit one of the most popular in Denmark. Surrounded by water and woodland, Egeskov embodies as few places do the landscape of castles and manor farms that gave Funen its fame as the kingdom's garden.
Jutland, the only mainland part of Denmark, joined to Germany in the south, is the country's historic cradle. Here, in the village of Jelling, the first kings of the dynasty that unified Denmark —Gorm the Old and his son Harald Bluetooth— left their monument in the 10th century: two enormous burial mounds, a church and two runestones. The larger one, carved around 965, proclaims that Harald won "all Denmark and Norway" and made the Danes Christian, which is why it is known as the country's birth certificate. The Jelling site is a Unesco World Heritage Site and an unavoidable starting point for Danish history.
Geography shaped Jutland's character. Its western coast, beaten by the North Sea, is a succession of dunes, endless beaches and treacherous sandbanks that caused countless shipwrecks over the centuries. Its interior, once covered by vast barren heaths, was transformed after the defeat of 1864 through an epic campaign of cultivation and afforestation inspired by the motto "what is lost without will be won within". The peninsula today holds much of the farming, the pig production and the wind power industry that made Denmark prosperous.
Jutland also holds the country's most impressive archaeological finds: it was in its peat bogs that the Iron Age "bog men" appeared, such as Tollund Man, preserved for two millennia, and the great ritual cauldron of Gundestrup. From its coasts sailed many of the Vikings who colonised England, and on it rose trading towns as old as Ribe and Hedeby. Mainland, vast and with a strong identity, Jutland is at once the oldest Denmark and the most productive.
On the west coast of Jutland, Ribe claims the title of oldest town in Denmark and in all of Scandinavia. It was born around the year 700 as a seasonal trading centre of the Viking age, where craftsmen and merchants exchanged amber, glass beads, furs and metals on the banks of the river. Its age and its early commercial importance made it one of the first bridgeheads of Christianity in the north: the missionary Ansgar, the "apostle of the North", preached here in the 9th century, and one of the country's first churches was built here.
In the Middle Ages, Ribe was a prosperous port and an important episcopal seat, with a Romanesque stone cathedral —the stone brought by sea from the Rhineland— that still dominates the town. The old centre, with its cobbled streets, its half-timbered houses leaning with the centuries and its old marketplace, survives almost intact and carries the visitor back to medieval and early modern Denmark. The night watchman still walks the streets at dusk, as he did centuries ago.
Ribe's history also has its dark side. During the 16th and 17th centuries, at the height of the witch-hunt hysteria that swept Europe, the town was the scene of famous trials: the best remembered of its victims, Maren Spliid, accused of witchcraft, was burned alive in 1641. A town museum recalls that persecution today. Between its Viking past, its medieval splendour and its shadows, Ribe is a living compendium of thirteen hundred years of Danish history.
Denmark's second city has its roots in the Viking age. Founded around the 8th century under the name Aros —"river mouth"— it was a fortified settlement and a trading port on the east coast of Jutland; excavations have brought to light Viking walls, dwellings and objects that are displayed in the Moesgaard museum, one of the country's great archaeological museums, which also holds "Grauballe Man", another Iron Age bog body.
Through the Middle Ages, Aarhus grew around its cathedral —the longest in Denmark— and its bishopric. But it was in the 19th and 20th centuries that it became a major city, thanks to the railway, the port and industry, and above all a university and cultural centre. Its university, founded in 1928, and its young atmosphere have made it the most dynamic city in Jutland.
That vitality shows in two emblematic institutions. Den Gamle By ("the Old Town") is a pioneering open-air museum, founded in 1914, which brings together dozens of historic houses moved from all over the country to recreate a Danish town of other eras, street by street. And the ARoS art museum, crowned by Your Rainbow Panorama, artist Olafur Eliasson's circular walkway of glass in every colour, has become a symbol of the city. In 2017, Aarhus was European Capital of Culture, confirming its role as a creative counterweight to Copenhagen.
In northern Jutland, on the shore of the Limfjord —the arm of sea that crosses the peninsula from side to side— Aalborg was for centuries a crossroads and a first-rate port. Its position beside the fjord crossing already made it important in the Viking age: very close by, at Lindholm Høje, lies one of the largest Viking and Iron Age cemeteries in Scandinavia, with hundreds of graves marked by stones set in the shape of ships, a site buried by sand and rediscovered in the 20th century.
In the early modern period, Aalborg enjoyed a golden age thanks to the Limfjord herring trade and to its port, which made it one of the richest cities in the kingdom; from those centuries remain Renaissance merchants' houses, such as that of Jens Bang, and a castle. Later came industry —cement, tobacco and, above all, Aalborg aquavit, the famous Danish akvavit— and a strong working-class tradition that earned it the nickname of the "red city".
Like so many industrial cities in northern Europe, Aalborg reinvented itself when the old industry declined. Its former port and factory areas beside the fjord have been transformed into a modern waterfront with cutting-edge architecture, such as the House of Music and the Utzon cultural centre —the work of the Danish architect Jørn Utzon, designer of the Sydney Opera House and a native of the city. Within a few metres, Aalborg thus combines its stone Viking ships, its merchant mansions and its 21st-century waterfront.
At the northernmost tip of Denmark, where the Jutland peninsula narrows until it disappears into the sea, lies Skagen. At its point, the cape of Grenen, a unique natural spectacle takes place: the meeting of two seas, the Skagerrak and the Kattegat, whose currents collide and form a line of clashing waves visible to the naked eye. For centuries, Skagen was a remote fishing village battered by wind and sand —the shifting sand once buried a church completely, and its tower still rises above the dunes— a hard, isolated community that lived off a dangerous and very busy sea.
Everything changed at the end of the 19th century, when a group of artists discovered Skagen. Drawn by its exceptional light —clean, golden, reflected by the sea and the sand— and by the simple life of the fishermen, painters such as Peder Severin Krøyer, Michael Ancher and Anna Ancher settled in the village and formed the famous colony of the Skagen Painters, the best-known Danish school of painting. Their canvases of fishermen on the beach, artists' dinners and walks at dusk, bathed in that unmistakable light, became icons of Nordic art and today fill the Skagen Museum.
That double legacy —of the sea and of art— made Skagen a legendary place. The yellow houses with red roofs, the fishing tradition, the mixing of two seas and the memory of the painters draw crowds of visitors today, especially in summer, when the light that captivated the artists still turns the beaches of Denmark's northernmost cape to gold.
On the shore of the Little Belt, the strait that separates Jutland from the island of Funen, Fredericia is a town conceived from scratch as a fortress. It was founded in 1650 by King Frederik III —from whom it takes its name— at a strategic point to defend the passage between the peninsula and the islands, after the devastating wars with Sweden. It was laid out on a grid plan surrounded by an imposing belt of walls, moats and earth bastions, which survive almost intact today and can be walked: one of the best examples of 17th-century fortification in northern Europe.
To populate the new town quickly, the crown offered something unheard of for the time: religious freedom and asylum. Fredericia thus took in French Huguenots, Catholics and, notably, one of the first Jewish communities in Denmark, who built their own places of worship and cemeteries. That exceptional tolerance, dictated by the need to repopulate the stronghold, gave the town a cosmopolitan character that was rare in the Lutheran Denmark of the day.
Fredericia entered the national epic on 6 July 1849, during the First Schleswig War. Besieged by German troops, the Danish garrison made a great surprise sortie that broke the encirclement and ended in a resounding victory, celebrated as one of the country's great feats of arms; a monument to the "brave soldier" (Den tapre landsoldat) commemorates it in the town. Between its green ramparts, its history of tolerance and its memory of war, Fredericia condenses several chapters of Danish military and social history.
In the middle of rural Jutland, the small town of Billund is known all over the world for a toy. There, in 1932, a carpenter named Ole Kirk Kristiansen, hit by the economic crisis, began making wooden toys in his workshop. In 1934 he named his company LEGO, a contraction of the Danish words "leg godt", "play well". By chance, in many languages the word also means "I put together" in Latin.
The decisive leap came after the Second World War, when the company bet on the new material, plastic. In 1958 it patented the coupling system of its bricks —the characteristic studs and tubes that let the pieces join firmly and come apart again an infinite number of times— the brilliant idea that turned LEGO into an open building system rather than a simple toy. From the small workshop of a carpenter in Billund came one of the most valuable and best-loved brands on the planet, still in the hands of the founding family.
In 1968, next to the factory, the company opened Legoland, the theme park built entirely from millions of bricks, with scale reproductions of cities and monuments from around the world. It was the first of a network of parks that today spans several continents. Billund, which grew at the pace of the company until it had its own international airport, is Denmark's family destination par excellence and a symbol of how creativity and design —two Danish hallmarks— can spring from the most unexpected place.
Before Copenhagen existed, the centre of Danish power was Roskilde, on the shore of a Zealand fjord. Tradition links its founding to Harald Bluetooth himself in the 10th century, and through the Middle Ages it was the most important city in the kingdom: royal capital and powerful episcopal seat, with as many as a dozen churches and monasteries. Its cathedral, begun around 1170 in brick, was the first great brick Gothic church in Scandinavia and is today a Unesco World Heritage Site.
Roskilde cathedral is, above all, the mausoleum of the Danish monarchy. Since the 15th century, almost every king and queen of Denmark has been buried there —close to forty monarchs— in chapels and sarcophagi spanning centuries of styles, from Gothic to modern. Walking its aisles means walking the entire genealogy of the oldest kingdom in Europe, from Queen Margrete I, architect of the Kalmar Union, to the sovereigns of the contemporary era.
Roskilde lost its capital status to Copenhagen in the 15th century, but it returned to history through another door: it was here that the humiliating Treaty of Roskilde of 1658 was signed, by which Denmark ceded Scania to Sweden. And in its fjord, archaeologists recovered in 1962 the famous Skuldelev ships, five Viking vessels deliberately sunk around the year 1070 to block the channel, now on display in the Viking Ship Museum, where replicas are built and sailed using period techniques.
Copenhagen began as a modest fishing village until, in 1167, the warrior bishop Absalon built a fortress on the islet where the parliament stands today, to protect the strait and fight the Baltic pirates. The location was unbeatable: a sheltered natural harbour on the trade route between the Baltic and the North Sea. Its name comes from that mercantile vocation, København, "the merchants' harbour". The city grew on the herring trade and, despite the sieges and raids of the Hanseatic League, which saw it as a rival, kept prospering.
In the 15th century, under Eric of Pomerania, Copenhagen became the capital of the kingdom, a status it would never lose. With the Reformation, absolutism and the reign of Christian IV it rose to the rank of a great European capital, with palaces, walls, shipyards and a university. It was the political, economic and cultural heart of Denmark and of its maritime empire, the city from which Norway, Iceland and the overseas colonies were governed.
Modern Copenhagen carries the scars and the splendours of that history: the British bombardments of 1807, the great fires that devastated the old town, the demolition of the walls in the 19th century that allowed the city to expand, and its contemporary reinvention as one of the world's most admired capitals for its design, its cycling culture and its quality of life. From the Nyhavn canal, with the coloured houses where Andersen lived, to the Little Mermaid statue inspired by his tale, the city shows the layers of its past at every step.
Much of Copenhagen's historic face is the work of a single king: Christian IV (1588-1648). Passionate about architecture, he gave the capital some of its best-loved monuments: Rosenborg Castle, a small red-brick Renaissance palace surrounded by gardens that today holds the Danish crown jewels; the Stock Exchange (Børsen), with its unmistakable spire of four intertwined dragon tails; and the Round Tower (Rundetårn), an observatory with a helical ramp up which, legend says, Tsar Peter the Great rode on horseback. He also founded the Christianshavn district, laid out along canals in the Dutch style.
Two centuries later, in the first half of the 19th century, Copenhagen was the stage of the Danish Golden Age. On its streets crossed Hans Christian Andersen, the philosopher Søren Kierkegaard —who barely left the city and turned it into the laboratory of his thought—, the sculptor Thorvaldsen, who left his work to a municipal museum, and a generation of painters who portrayed the light and the bourgeois life of the capital. It was a time of cultural splendour amid the material poverty that followed the Napoleonic wars.
That heritage lives today alongside institutions born of industry and philanthropy, such as the Carlsberg brewery, whose founder funded museums, castle restorations and Danish science. In a few square kilometres Copenhagen thus holds the royal palace of Amalienborg, the Tivoli Gardens —one of the oldest amusement parks in the world, opened in 1843— and the free town of Christiania, a symbol of 1970s counterculture: successive layers of a capital that has never stopped reinventing itself.
At the narrowest point of the Øresund strait, where barely four kilometres of sea separate Denmark from Sweden, Kronborg castle rises at Helsingør. Its origin is purely economic: from 1429, King Eric of Pomerania required every ship wanting to enter or leave the Baltic to pay a toll, the "Øresundstold" or Sound Dues. For more than four centuries, that toll —collected under the threat of the castle's guns— was one of the greatest sources of income for the Danish crown and one of the keys to its power.
To watch over and collect that levy, King Frederik II rebuilt the old medieval fortress between 1574 and 1585 and turned it into Kronborg, a dazzling Renaissance castle that astonished the Europe of its time. With its copper towers, its halls and its great ballroom, it was at once a military fortress and a prestige palace, a symbol of Danish control over the entrance to the Baltic. Today it is a Unesco World Heritage Site.
Kronborg owes its universal fame to literature. William Shakespeare, who probably never saw it but knew its reputation, set there —the "Elsinore" of his play— the tragedy of Hamlet, Prince of Denmark. Ever since, the castle has been tied for ever to the figure of the tormented prince, and every summer Hamlet is performed within its walls. Beneath the castle, legend also places Holger Danske (Holger the Dane), the sleeping hero who will wake when Denmark is in danger: a national symbol that the anti-Nazi resistance took as its code name.
In Hillerød, north of Copenhagen, Frederiksborg castle rises on three islets in a lake, the masterpiece of the Danish Renaissance. Christian IV had it built at the start of the 17th century on an earlier residence of his father Frederik II, from whom it takes its name. With its towers, its spires, its facades of red brick and sandstone and its courtyards reflected in the water, Frederiksborg was conceived as a demonstration of the grandeur of the monarchy, and for centuries it was the place where Danish kings were anointed.
In 1859, a devastating fire gutted much of the castle's interior. Its reconstruction became a national cause, and here an unexpected name enters the scene: J.C. Jacobsen, founder of the Carlsberg brewery, who funded much of the work and proposed turning the restored castle into a museum. So, in 1878, the Museum of National History of Denmark was born, supported by the Carlsberg Foundation.
Today Frederiksborg houses the country's largest collection of portraits and history painting: century by century, its rooms run through the history of Denmark in the faces of its kings, nobles, artists and scientists, under gilded ceilings and tapestries. The baroque gardens, with their symmetrical parterres and their cascades, complete an ensemble that sums up, in a single place, Danish monarchical ambition and national memory.
At the eastern end of the small island of Møn, the white cliffs of Møns Klint drop sheer into the Baltic from more than a hundred metres up, in one of the most spectacular landscapes in Denmark. They are walls of chalk —pure calcium carbonate— formed some 70 million years ago, in the Cretaceous, by the build-up on the sea floor of the microscopic skeletons of trillions of algae. The advance of the glaciers during the last ice age lifted and folded those layers until they stood upright, leaving them exposed to the sea; fossils of sea urchins, belemnites and other marine animals are abundant at the foot of the cliff.
The island of Møn also holds a medieval artistic treasure. Its rural churches —above all those of Elmelunde, Fanefjord and Keldby— preserve extraordinary 15th-century Gothic frescoes, painted on the vaults by an anonymous workshop known as the "Elmelunde Master". With lively and often folksy strokes, they tell biblical scenes for a congregation that could not read, and they form one of the richest bodies of medieval wall painting in northern Europe.
In recent times, Møn has added another distinction: in 2017 it was designated an International Dark Sky Park and Community, the first in Scandinavia, for the exceptional absence of light pollution that lets you contemplate the stars and, with luck, the Milky Way. Between the chalk cliffs, the beech woods, the frescoes in its churches and its night skies, Møn offers a Denmark that is at once natural, spiritual and luminous, very different from the bustle of the capital.
