Cameroon–Gabon border

A short line along the Kyé, Ntem, Kom and Ayina rivers, fixed by France and Germany in 1908. In 1911 Germany pushed Cameroon’s border far to the south, but after World War I the line went back to where it was.

German Kamerun, French Congo

Germany proclaimed a protectorate over Kamerun in July 1884, and a Franco-German protocol of 24 December 1885 ran the line inland along the Campo river and then a parallel, later fixed at 2°10′20″ north. A Franco-German convention of 1908 redrew the whole Kamerun–French Congo border; its line along the Kyé, Ntem, Kom and Ayina rivers is today’s Cameroon–Gabon border.[1]

Just before World War I, a convention of 4 November 1911 moved the border with Gabon considerably south, as part of a deal that gave Germany land from French Equatorial Africa. After the war that land was returned to French Equatorial Africa, and the 1908 line came back.[1]

Independence

The League of Nations gave France and Britain mandates over Cameroon in 1922. French Cameroun became independent on 1 January 1960 and joined the former British Southern Cameroons on 1 October 1961. Gabon proclaimed independence on 17 August 1960.[1]
