Burkina Faso–Ivory Coast border

[2] France occupied this area in 1900; Mali (then referred to as French Sudan) was originally included, along with modern Niger and Burkina Faso, within the Upper Senegal and Niger colony and (along with Ivory Coast) became a constituent of the federal colony of French West Africa (Afrique occidentale française, abbreviated AOF).

[4][2] During the period 1932–47 Upper Volta was abolished and its territory split out between French Sudan, Niger and Ivory Coast, with the latter gaining the bulk of the territory, re-named "Haute Côte d'Ivoire".

[2][4] The precise date the Ivory Coast–Upper Volta boundary was drawn appears to be uncertain – it is thought to have been drawn at the time of the formal institution of Upper Volta in 1919, based upon the rough delimitation of Ivorian territory by France in 1899.

[2][4] As the movement for decolonisation grew in the post-Second World War era, France gradually granted more political rights and representation for their sub-Saharan African colonies, culminating in the granting of broad internal autonomy to French West Africa in 1958 within the framework of the French Community.

[6] Eventually, in 1960, both Ivory Coast and Upper Volta gained independence, and their mutual frontier became an international one between two states.
