Guinea–Liberia border

It then proceeds in this direction via a series of overland and riverine (such as the Djoule and Mani) sections, turning to the northeast and then finally southeast to the Ivorian tripoint on Mount Nuon in the Nimba Range.

[2] Liberia was founded as a colony for freed American slaves in 1822; various settlements were founded along the coast in the following years, with the bulk of them uniting to create the Republic of Liberia in 1847 (the Republic of Maryland joined later in 1857).

[3][4] France had also taken an interest in the West African coast, settling in the region of modern Senegal in the 17th century and later annexing the coast of what is now Guinea in the late 19th century as the Rivières du Sud colony.

[4] As the African interior began to be carved up during the Scramble for Africa in the 1880s, France and Liberia signed a boundary treaty on 8 December 1892 outlining their respective territorial limits (for France, this treaty covered what would later become the Ivory Coast as well as Guinea).

The difficulties with demarcating this boundary on the ground led France and Liberia to conclude another treaty on 18 September 1907, confirmed in January 1911, which moved it south to its current position.
