The region of Southern Sudan (currently the independent republic of South Sudan) became autonomous for the first time, within Sudan, in 1972, through the Addis Ababa Agreement meant to end the First Sudanese Civil War, and its local government had five presidents until 1983, when the Sudanese central government revoked the autonomy. Autonomy was gained again in 2005, through the Comprehensive Peace Agreement meant to end the Second Sudanese Civil War, and the position of president of Southern Sudan was restored. Then, on 9 July 2011, South Sudan became independent and a new constitution was adopted.[1]
