The Emin Pasha Relief Expedition of 1887 to 1889 was one of the last major European expeditions into the interior of Africa in the nineteenth century. Led by Henry Morton Stanley, its goal was ostensibly the relief of Emin Pasha, the besieged Egyptian governor of Equatoria, who was threatened by Mahdist forces.

Sir Henry Morton Stanley was a Welsh-American explorer, journalist, soldier, colonial administrator, author and politician who was famous for his exploration of Central Africa and his search for missionary and explorer David Livingstone. Besides his discovery of Livingstone, he is mainly known for his search for the sources of the Nile and Congo rivers, the work he undertook as an agent of King Leopold II of the Belgians which enabled the occupation of the Congo Basin region, and his command of the Emin Pasha Relief Expedition. He was knighted in 1897, and served in Parliament as a Liberal Unionist member for Lambeth North from 1895 to 1900.
