The flag of South Sudan was adopted following the signing of the Comprehensive Peace Agreement that ended the Second Sudanese Civil War. A different version of the flag was previously used as the flag of the Sudan People's Liberation Movement. The flag of South Sudan predates the country, as the flag was adopted in 2005, while the country became independent in 2011.
