Which European powers had frontier disputes with Liberia during the early republic?

During the early years of the Republic of Liberia, the nation faced persistent frontier disputes with two primary European powers:

• France: Conflicts occurred along the border with the Ivory Coast. These tensions were addressed through a treaty in 1892, and later, in 1919, Liberia ceded approximately 2,000 square miles of its claimed hinterland to France because it could not effectively exert authority over the region.12
• Great Britain: Disputes arose regarding the border with Sierra Leone. Efforts to resolve these issues led to a treaty with Great Britain in 1885.12

These challenges were largely a result of the young republic's struggle to extend and maintain its authority over the interior and coastal areas it claimed during the 19th century.12
