Greenland

• 1. Introduction

  ›

  Greenland holds the lowest temperature ever recorded in the Northern Hemisphere: -69.6 C, measured near the topographic summit of its ice sheet on the 22nd of December 1991. The numbers attached to this place strain belief. It is the world's largest island, with a total area of 2,166,086 square kilometres. The Greenland ice sheet alone covers 1,755,637 of those, or 81 percent. Yet only 56,542 people lived here in 2025, making it the least densely populated country in the world. This is a land of contradictions. It sits on the continent of North America, but for centuries it answered to European crowns. Its name promises green, but ice defines it. How did a Norwegian exile come to name an icy land Greenland? Why did a Norse population vanish after 400 years? And why, in 2025, would the United States threaten to annex it? The answers run through Viking sagas, Cold War secrets buried in ice, and a fertility transition unlike any other on record.

• 2. A Name To Lure Settlers

  ›

  Erik the Red, according to the Icelandic sagas, was exiled from Iceland alongside his father Thorvald, who had committed manslaughter. With his extended family and his thralls, Erik sailed for an icy land known to lie to the northwest. The Saga of Erik the Red records his marketing instinct plainly. In the summer, it states, Erik left to settle in the country he had found, which he called Greenland, as he said people would be attracted there if it had a favourable name. The pleasant name was, in other words, a deliberate lure. The island carries a second name too, far older to its native people. In the Greenlandic language it is Kalaallit Nunaat. The Kalaallit are the principal group of Greenlandic Inuit who inhabit the western region. The term Nunaat carries a precise meaning. It refers to land, and it does not include waters and ice. For a place that is four-fifths frozen, this is no small distinction.

• 3. The Vanished Norse

  ›

  From the year 986, fourteen boats led by Erik the Red carried Icelanders and Norwegians to the west coast. They built three settlements near the southwestern tip of the island: the Eastern Settlement, the Western Settlement, and the Middle Settlement. Brattahlíð and other Norse settlements thrived for centuries. Between AD 800 and 1300, the fjords of southern Greenland enjoyed a relatively mild climate, several degrees Celsius warmer than usual in the North Atlantic. Barley was grown as a crop up to the 70th parallel. Then the warmth withdrew. A study of North Atlantic temperatures during the Little Ice Age found maximum summer temperatures dropping as much as 6 to 8 degrees below modern levels around the turn of the 14th century. The lowest winter temperatures of the last 2,000 years fell in the late 14th and early 15th centuries. The demise of the Western Settlement lines up with this cooling. Theories abound for why the Norse disappeared during the 14th and early 15th centuries. Excavations at Herjolfsnes in the 1920s suggested malnutrition, with bones pointing to soil erosion from farming, turf-cutting, and wood-cutting. The Icelandic Annals record that in 1379 the Skrælings killed 18 Norse Greenlanders. Skræling was the Norse word for the Inuit, meaning wretches. More recent evidence complicates the starvation story. The Norse, who never numbered more than about 2,500, may have left gradually over the 15th century as walrus ivory, their most valuable export, lost value to higher-quality competitors. One account blamed their fate on hidebound thinking, on a refusal to borrow the apparel and hunting gear the Inuit used against the cold and damp.

• 4. The Thule Inheritance

  ›

  The Thule people are the ancestors of today's Greenlandic population, and they came from far away. They migrated eastward from what is now Alaska around 1000 AD, reaching Greenland around 1300. They descended from the Birnirk culture of Siberia, and they completely replaced the earlier Paleo-Eskimos. No genes from the Palaeo-Inuit Dorset culture survive in Greenland's present population. The Thule brought tools that changed survival in the Arctic. They were the first to introduce dog sleds and toggling harpoons to Greenland. A 2015 genetic study confirmed the deep continuity of this lineage. Modern Inuit in Greenland are direct descendants of those first Thule pioneers, with roughly 25 percent admixture from European colonizers of the 16th century. Despite old speculation, the study found no evidence of Viking settlers among their predecessors.

• 5. From Portuguese Maps To Hans Egede

  ›

  In 1500, King Manuel I of Portugal sent Gaspar Corte-Real to Greenland in search of a Northwest Passage to Asia. Under the Treaty of Tordesillas, this fell within Portugal's sphere of influence. Corte-Real returned in 1501 with his brother Miguel, found the sea frozen, and sailed south to Labrador and Newfoundland. Their cartographic information fed into the Cantino planisphere, made in Lisbon and presented to Ercole I d'Este, Duke of Ferrara, by Alberto Cantino in 1502. That map accurately depicts Greenland's southern coastline. King Christian IV of Denmark and Norway tried next. Between 1605 and 1607 he sent expeditions to find the lost eastern Norse settlement and assert sovereignty. The English explorer James Hall served as pilot on all three. The voyages mostly failed, partly because their leaders were told to search the east coast just north of Cape Farewell, nearly inaccessible due to southward drifting ice. Permanent reconnection came through a missionary. In 1721 Hans Egede led a joint mercantile and clerical expedition, not knowing whether any Norse civilization remained. He found none. After 15 years he left his son Paul Egede in charge and returned to Denmark to establish a Greenland Seminary. The colony centred on Godthåb, meaning Good Hope, which is today's Nuuk.

• 6. War, Cold War, And Ice Secrets

  ›

  On the 9th of April 1940, early in World War II, Greenland's connection to Denmark was severed after Nazi Germany occupied the Danish homeland. The United States stepped in, occupying Greenland on the 8th of April 1941 to guard against a German invasion, and staying until 1945. Greenland funded its purchases from the United States and Canada by selling cryolite from the mine at Ivittuut. The Americans code-named the island Bluie, with bases like Bluie West-1 at Narsarsuaq and Bluie West-8 at Søndre Strømfjord, both still used as international airports. In 1946 the United States offered to buy Greenland outright. Denmark firmly rejected the offer, viewing the island as integral to its history and national identity. The 1951 Greenland Defense Agreement instead let the United States keep its bases, and Thule Air Base was greatly expanded between 1951 and 1953. The local population of three nearby villages was moved more than 100 kilometres away in the winter. Beneath the ice lay a stranger ambition. The United States tried to build a subterranean network of secret nuclear missile launch sites in the ice cap, named Project Iceworm, managed from Camp Century between 1960 and 1966 before being abandoned as unworkable. The Danish government did not learn of the mission until 1997, while searching declassified files for records of a nuclear-equipped B-52 bomber that crashed near Thule in 1968. That crash, on the 21st of January 1968, involved four nuclear bombs and caused extensive radioactive contamination. One of the H-bombs remains lost.

• 7. The Long Road To Self-Rule

  ›

  The 1953 Danish constitution ended Greenland's colonial status, incorporating the island into the Danish realm as an amt, a county, and extending Danish citizenship to Greenlanders. What followed was a strategy of cultural assimilation. Housing and infrastructure expanded in the Danish mold to draw people from villages into urban centres. The Blok P development in Nuuk, Denmark's largest, came to house nearly 1 percent of the population before its unsuitability led the government to demolish it in 2012. Danish became the language of official matters, and many Greenlandic children grew up in boarding schools in southern Denmark, some losing their cultural ties. The Greenlandic elite pushed back. A movement for independence peaked in the 1970s, and political complications around Denmark's entry into the European Common Market led to the Home Rule Act of 1979. A referendum held on the 17th of January 1979 granted limited autonomy, taking effect on the 1st of May. In 1985 Greenland left the European Economic Community, objecting to its commercial fishing rules and a ban on sealskin products. Devolution deepened in the 21st century. Voters approved greater autonomy on the 25th of November 2008, and on the 21st of June 2009 Greenland gained self-rule over judicial affairs, policing, and natural resources. Greenlanders were recognized as a separate people under international law. That same year, Greenlandic was declared the sole official language at a historic ceremony. Denmark still controls citizenship, monetary policy, security, and foreign affairs, and pays an annual block grant. As Greenland collects revenue from its own resources, that grant is meant to shrink, a step generally seen as moving toward eventual full independence.

• 8. Ice, Wealth, And A Coveted Island

  ›

  Sixty-seven percent of Greenland's electricity comes from renewable energy, mostly hydropower, and education and healthcare are free. LGBTQ rights here are among the most extensive in the world, with legal gender changes based on self-determination allowed since a 2016 decree. Yet the island carries painful history too. From 1966 to 1974, Danish doctors fitted roughly 4,500 Greenland Inuit women and girls with intrauterine devices, about half of all fertile females. Some girls as young as 12 were taken from school without their parents' permission. Fertility rates fell from 7 to 2.3 children per woman over eight years, the fastest fertility transition on record in human history. In 2022 Danish Health Minister Magnus Heunicke announced an investigation. The economy still leans heavily on Denmark and on fish. The 2024 block grant was 4.3 billion kroner, a third of public revenue, and fishing accounts for more than 90 percent of exports. The promise of mineral riches has proven elusive. The New York Times reported in March 2025 that despite dozens of exploratory projects, only two mines were active. China accounts for 95 percent of the world's current rare-earth supply, and economist Torben M. Andersen judged in January 2025 that mining would not matter much to Greenland's economy for at least ten years. Now the climate itself is rewriting the map. After 1996, Greenland has not had a single year without losing ice mass on average. During a 2021 melting event, rain fell at Greenland's highest point for the first time in recorded history, so unexpectedly that the summit station had no rain gauges. The melting ice, the mineral hopes, and the position between Eurasia, North America, and the Arctic have made Greenland strategically vital. Since 2025, the United States has pursued threats to annex it, triggering the Greenland crisis. The same island Erik the Red named to attract settlers now draws a superpower's gaze, and the question of who will hold it remains open.
