Executive summary

Yes — Denmark has sold territory to the United States in the past: Copenhagen transferred the Danish West Indies (today’s U.S. Virgin Islands) to Washington in 1917 in a transaction shaped by strategic concerns as well as economic realities [1] [2]. Later 20th‑century episodes show recurring U.S. interest in Danish possessions (notably Greenland), but those efforts resulted in offers, strategic agreements and political rows rather than additional sales [3] [4] [5].

1. The 1917 sale that reshaped a Caribbean map

In January 1917 Denmark sold the Danish West Indies — the islands of St. Thomas, St. John and St. Croix — to the United States for $25 million in gold, a formal transfer of sovereignty that created today’s U.S. Virgin Islands [1] [2] [6]. American policymakers had long eyed the islands’ excellent harbor and Caribbean position as a naval and strategic outpost, especially as the Panama Canal neared completion, and wartime fears about German expansion accelerated negotiations that had simmered for decades [2] [7].

2. Strategy and economics: why Denmark agreed to sell

Denmark’s willingness to part with the islands reflected more than mere cash: the colonies had become economically burdensome and offered limited strategic value to Copenhagen, while the United States valued them as insurance against hostile powers in the Western Hemisphere — an explicitly strategic motive cited in contemporary and retrospective accounts [6] [7] [2]. The transaction fits a pattern of early‑20th‑century geopolitics where territory transfers were instruments of great‑power strategy as well as economic calculations [6].

3. Greenland: repeated offers and a firm Danish refusal

Unlike the Danish West Indies, Greenland has not been sold to the United States despite periodic U.S. bids: President Truman’s administration secretly floated a purchase in 1946 and U.S. officials at times considered offers around $100 million in gold, reflecting perceived military necessity during the early Cold War [3] [4]. Denmark rejected such proposals, and Greenland’s evolving legal and political status — including home rule and later self‑government — complicates any simple analogies to the 1917 sale [3] [6].

4. Strategic access without transfer: defence pacts and bases

The U.S. has frequently secured strategic access to Danish territories through agreements rather than purchases; for example, a 1951 defence accord with Denmark grants rights to construct and operate bases in Greenland — a form of practical control that stopped short of sovereignty transfer [5]. Those arrangements show how strategic imperatives can be satisfied through military and diplomatic means without buying land outright [5].

5. Modern politics, satire and misinformation around “buying”

Recent public drama — including proposals by U.S. political figures to acquire Greenland and satirical counterclaims that Denmark offered to buy the United States — has blurred fact and fiction, prompting fact‑checks that trace viral stories to satire [8] [9]. News coverage and polling also reveal political backlash in Denmark and Greenland, with leaders insisting territories are not for sale and publics mobilizing satirical petitions and protests [10] [11].

6. What the historical record actually shows and what it does not

The clear historical fact is the 1917 sale of the Danish West Indies to the U.S., motivated in part by strategic U.S. concerns and Danish economic calculations [1] [2] [6]. The record also documents U.S. attempts to buy Greenland and high‑level strategic planning that weighed purchase versus other forms of control [3] [4]. What the sources do not show is any other completed sale of Danish sovereign territory to the United States beyond 1917; claims to the contrary often rest on satire, misinformation, or conflation of offers and defense arrangements [9] [8].

7. Hidden agendas and competing perspectives

Behind the transactions and proposals lie competing agendas: U.S. strategic planners aiming to deny rivals access and secure Arctic routes, Danish interests balancing colonial legacies and economic burdens, and Greenlandic assertions of self‑determination resisting commodification of land [7] [6] [3]. Journalistic and scholarly sources highlight these tensions — from pragmatic statecraft in 1917 to the modern politics of sovereignty, defense and identity — underscoring that “sale” is only one of several instruments great powers use to secure strategic advantage [2] [5] [6].
