South Sudan is a landlocked autonomous region in the southern part of the Sudan. The region's autonomous status is a condition of a peace agreement between the Sudan's People's Liberation Army 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. A referendum on independence for Southern Sudan was held in January 2011, with 98.83% of the electorate opting for secession. The President of Sudan accepted the results and issued a Republican Decree confirming the outcome. South Sudan became an independent country on 9 July 2011.
