Benin–Burkina Faso border

[1] The border starts at the Togolese tripoint, then proceeds briefly overland in a north-western direction, before reaching the Pendjari River, which it then follows for some distance.

France began occupying the area of modern Mali (then often referred to as French Sudan) and Burkina Faso (then called Upper Volta) during the 1880s-90s.

[4] This region was organised as Upper Senegal and Niger; various French decrees delimited a border between this colony and Dahomey during the period 1901–14.

As a result, the two countries signed an agreement in May 2009 which created a small neutral zone in the area, pending a final decision on the matter by the International Court of Justice.

[6][7] In recent years the boundary region had been affected by the ongoing Islamist insurgency in the Sahel, predominantly on the Burkinabe side of the border.
