passage: Southern Sudan Autonomous Region (2005–11)
Southern Sudan ( "Ḥukūmat Janūb al-Sūdān") was an autonomous region consisting of the ten southern states of Sudan between its formation in July 2005 and independence as the Republic of South Sudan in July 2011. The autonomous government was initially established in Rumbek and later moved to Juba. It was bordered by Ethiopia to the east; Kenya, Uganda, and the Democratic Republic of the Congo to the south; and the Central African Republic to the west. To the north lies the predominantly Arab and Muslim region directly under the control of the central government. The region's autonomous status was a condition of a peace agreement between the Sudan People's Liberation Army/Movement (SPLA/M) and the Government of Sudan represented by the National Congress Party ending the Second Sudanese Civil War. The conflict was Africa's longest running civil war.
