Discovered and claimed by Portugal in the late 15th century, the islands' sugar-based economy gave way to coffee and cocoa in the 19th century - all grown with plantation slave labor, a form of which lingered into the 20th century. Although independence was achieved in 1975, democratic reforms were not instituted until the late 1980s. The first free elections were held in 1991.
