Anglo-Portuguese Convention

The Anglo-Portuguese Convention of 1891 was a boundary treaty between the United Kingdom and Portugal. This agreement was part of a larger context of colonial claims in Africa, specifically concerning Portugal's ambition to connect its territories of Angola and Mozambique. Britain challenged these claims, leading to an ultimatum in January 1890 that forced Portugal to withdraw from disputed central African regions. The 1891 treaty, along with a subsequent one in 1899, helped to define the boundaries of Portugal's remaining colonies and reaffirmed the long-standing alliance between the two nations.12
