Chad–Niger border
international border
The Chad–Niger border is 1,196 km (743 mi) in length and runs from the tripoint with Libya in the north, to the tripoint with Nigeria in the south.
Description
The border consists of a series of mostly straight lines. The northern section of the boundary begins near the Tibesti Mountains at the Libyan tripoint and proceeds roughly south-eastwards; the border here cuts across the Massif d'Afafi and the Erg of Bilma. The middle section of the boundary slants to the south-west slightly, with the southern section continuing in a much more pronounced south-westerly direction down to Lake Chad, whereupon a straight line veering to the south-east connects the border to the Nigerian tripoint. The majority of border lies within the Sahara Desert, with the more southerly sections lying within the Sahel. The border region is very sparsely populated, there being no towns or villages in its immediate vicinity.
History
The border first emerged during the Scramble for Africa, a period of intense competition between European powers in the later 19th century for territory and influence in Africa. 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 of 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). From these bases the French explored further into the interior, eventually linking the two areas following expeditions in April 1900 which met at Kousséri in the far north of modern Cameroon.

Why this record matters
“Chad–Niger border” is worth following because a concise public description often conceals a longer documentary argument. Here, Chad, Niger and border provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 18, 2026. The linked authority identifier is Q3089174. Authority coordinates are 23.139, 14.996. None of the 2 selected statements returned an explicit reference. The first chronological checks are 1884 and 1900.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
