The current flag of Sudan was adopted on 20 May 1970 and consists of a horizontal red-white-black tricolour with a green triangle at the hoist. The flag is based on the Arab Liberation Flag of the Egyptian Revolution of 1952, as are the flags of Egypt, Iraq, Syria, Yemen, and Palestine and formerly of the United Arab Republic, North Yemen, South Yemen, and the Libyan Arab Republic.
The flag of South Sudan was adopted following the signing of the Comprehensive Peace Agreement that ended the Second Sudanese Civil War. A similar 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.
