When Emperor Haile Selassie unilaterally dissolved the Eritrean parliament and annexed the country in 1962, the Eritrean Liberation Front (ELF) waged an armed struggle for independence. The ensuing Eritrean War for Independence went on for 30 years against successive Ethiopian governments until 1991, when the Eritrean People's Liberation Front (EPLF), a successor of the ELF, defeated the Ethiopian forces in Eritrea and helped a coalition of Ethiopian rebel forces take control of the Ethiopian Capital Addis Ababa.
