Equatoria is the southernmost region of South Sudan, along the upper reaches of the White Nile and the border between South Sudan, Uganda, Kenya, and the Democratic Republic of the Congo. Juba, the national capital and the largest city in South Sudan, is located in Equatoria. Originally a province of Anglo-Egyptian Sudan, it also contained most of northern parts of present-day Uganda, including Lake Albert and West Nile. It was an idealistic effort to create a model state in the interior of Africa that never consisted of more than a handful of adventurers and soldiers in isolated outposts.
Equatoria was established by Samuel Baker in 1870. Charles George Gordon took over as governor in 1874, followed by Emin Pasha in 1878. The Mahdist Revolt put an end to Equatoria as an Egyptian outpost in 1889. Later British Governors included Martin Willoughby Parr. Important towns in Equatoria included Lado, Gondokoro, Dufile and Wadelai. The last two former areas of Equatoria, Lake Albert and West Nile are now situated in Uganda.
