Niger–Nigeria border

[1] The border starts in the west at Beninese tripoint in the Niger river, then proceeds overland in a northwards direction, before turning eastwards in a broad arc.

[4] 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.

[4] France has conquered the area of modern Niger in 1900; initially ruled as a military territory, it was later included within the federal colony of French West Africa (Afrique occidentale française, abbreviated AOF).

In 1900 rule of these areas was transferred to the British government, with the Northern and Southern (including Lagos and Calabar) protectorates united as the colony of Nigeria in 1914.

In recent years the border area has been heavily affected by the ongoing Boko Haram insurgency in north-east Nigeria, resulting in flows of cross-border refugees and a general state of lawlessness.
