The union was dissolved by the Treaty of Kiel in 1814; the Danish monarchy "irrevocably and forever" renounced claims to the Kingdom of Norway in favour of the Swedish king. Denmark kept the possessions of Iceland (which retained the Danish monarchy until 1944), the Faroe Islands and Greenland, all of which had been governed by Norway for centuries. Apart from the Nordic colonies, Denmark continued to rule over Danish India from 1620 to 1869, the Danish Gold Coast (Ghana) from 1658 to 1850, and the Danish West Indies from 1671 to 1917.
