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. Before the outbreak of a civil war in 2013, it was planned that the capital city would be moved to the more centrally located Ramciel in the future.

South Sudan became an independent state on July 9, 2011, following a referendum that passed with 98.83% of the vote. It is a United Nations member state, and a member state of the African Union, of the East African Community, and of the Intergovernmental Authority on Development. In July 2012, South Sudan signed the Geneva Conventions. South Sudan has suffered ethnic violence and has been in a civil war since 2013; as of 2017, it had the highest score on the Fragile States Index (formerly, the Failed States Index), surpassing Somalia.

South Sudan has an estimated population of 8 million, but, given the lack of a census in several decades, this estimate may be severely distorted. The economy is predominantly rural and relies chiefly on subsistence farming. Around 2005, the economy began a transition from this rural dominance, and urban areas within South Sudan have seen extensive development.
