It is bordered by Côte d'Ivoire (Ivory Coast) to the west, Burkina Faso to the north, Togo to the east, and the Gulf of Guinea to the south.

Trade with European states flourished after contact with the Portuguese in the 15th century, and the British established the Gold Coast Crown colony in 1874 over parts but not all of the country.

Yugoslavia

Yugoslavia is a term that describes three political entities that existed successively on the western part of the Balkans, during most of the 20th century. The first country to be known by this name was the Kingdom of Yugoslavia, which before 3 October 1929 was known as the Kingdom of Serbs, Croats and Slovenes. It was established on 1 December 1918 by the union of the State of Slovenes, Croats and Serbs and the Kingdom of Serbia (to which the Kingdom of Montenegro was annexed on 13 November 1918, and the Conference of Ambassadors in Paris gave international recognition to the union on 13 July 1922). The Kingdom of Yugoslavia was invaded by the Axis powers in 1941, and because of the events that followed, was officially abolished in 1943 and 1945.
