South Sudan officially the Republic of South Sudan, is a landlocked country in northeastern Africa that gained its independence from Sudan in 2011. Its current capital is Juba, which is also its largest city. It is planned that the capital city will be changed to the more centrally located Ramciel in the future. The territories of modern South Sudan and the Republic of the Sudan were occupied by Egypt under the Muhammad Ali Dynasty, and later governed as an Anglo-Egyptian condominium until Sudanese independence was achieved in 1956. Following the First Sudanese Civil War, the Southern Sudan Autonomous Region was formed in 1972 and lasted until 1983. A second Sudanese civil war soon developed and ended with the Comprehensive Peace Agreement of 2005. Later that year, southern autonomy was restored when an Autonomous Government of Southern Sudan was formed. South Sudan became an independent state on 9 July 2011, following a referendum that passed with 98.83% of the vote. In July 2012, South Sudan signed the Geneva Conventions. South Sudan has suffered internal conflict since its independence; it has the highest score on the Fragile States Index (formerly the Failed States Index).
