Central Equatoria is a state in South Sudan. With an area of 43,033 square kilometres (16,615 sq mi), it is the smallest of the original South Sudanese states. Its previous name was Bahr al-Jabal, named after a tributary of the White Nile that flows through the state. It was renamed Central Equatoria in the first Interim Legislative Assembly on 1 April 2005 under the government of Southern Sudan. Central Equatoria seceded from Sudan as part of the Republic of South Sudan on 9 July 2011. The state's capital, Juba, is also the national capital of South Sudan. On October 2, 2015, the state was split into three states: Jubek, Terekeka, and Yei River. The state of Central Equatoria was re-established by a peace agreement signed on 22 February 2020.
