Autonomy was withdrawn on 14 November 1962, following the beginning of the Eritrean War of Independence in 1961. After the Ethiopian revolution in 1974 the province was put under the reign of Derg and later the People's Democratic Republic of Ethiopia. The province achieved de jure independence under the Eritrean People's Liberation Front in 1991 and was officially abolished by Ethiopia in 1993, becoming the independent state of Eritrea.
