Danish West Indies - Wikipedia
The Danish West Indies (Danish: Dansk Vestindien or De dansk-vestindiske øer) or Danish Antilles was a Danish colony in the Caribbean, first under the united kingdoms of Denmark-Norway and later, after the 1814 Treaty of Kiel, Denmark alone. The islands were sold to the United States and were organized as the United States Virgin Islands in 1917. The Danish geographical name for the constituent islands is Jomfruøerne (lit. "The Virgin Islands").
