Burkina Faso–Niger border

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.

These areas came the control of the federal colony of French West Africa (Afrique occidentale française, abbreviated AOF).

[5] In August 1960 both Niger and Upper Volta (renamed Burkina Faso in 1984) gained full independence, and their mutual frontier became an international one between two sovereign states.

[3] On 23 June 1964 the two new governments met and formally agreed to settle their shared border, however it appears no final arrangement came out of these discussions[3] A full border demarcation remained incomplete until the late 1980s, however disputes about the interpretation of colonial-era boundary treaties prompted the two states to submit the dispute to the International Court of Justice in 2010.

[6][7] The ICJ subsequently ruled on the dispute in 2013, recommending some small territorial exchanges, which were accepted by both governments.
