In January 1792, the King issued a royal ordinance declaring the end of Danish slave exports as of 1 January 1803. Thus Denmark-Norway was the first European nation to abolish its export slave trade. However, that reputation was tainted by the export of some 30,000 Africans during the last decade of legal commerce in slaves. Moreover, illicit slave trading continued from Danish forts, particularly Fort Fredensborg, until the 1830s and - 1840s. Slavery in the Danish West Indian colonies was abolished after a rebellion on July 3, 1848. In 1917 the three West Indian islands were sold to USA and renamed the U.S. Virgin Islands.
