On March 31, 1917, the U.S. took formal possession of the Danish West Indies. Renamed the Virgin Islands, this chain consists of St. Thomas, St. Croix, St. John and about fifty other small islands, most of which are uninhabited. Lying about sixty-five kilometers east of Puerto Rico at the end of the Greater Antilles, the U.S. purchased the islands from Denmark for $25 million because of their strategic location in relation to the Panama Canal.

Many different groups have claimed ownership of these islands. When Christopher Columbus landed on St. Croix in 1493 the islands were occupied by the native Carib Indians.
