Central African Republic–Democratic Republic of the Congo border

[3] The process culminated in the Berlin Conference of 1884, in which the European nations concerned agreed upon their respective territorial claims and the rules of engagements going forward.

As a result of this France gained control the upper valley of the Niger River (roughly equivalent to the areas of modern Mali and Niger), and also the lands explored by Pierre Savorgnan de Brazza for France in Central Africa (roughly equivalent to modern Gabon and Congo-Brazzaville).

[4] The boundary between French and Belgian territory was somewhat vaguely delimited at the time of the Conference, utilising the Congo River and then various lines of latitude and longitude.

[3][2] In the following years France explored further into the interior, founding Bangui in 1889, and eventually linking their Central and West African holdings following expeditions in April 1900 which met at Kousséri in the far north of modern Cameroon.

[3][2] Administration of the Congo Free State was taken over by the Belgian government in 1908 following controversies engendered by the atrocities committed by Leopold's forces there.
