Eritrean War of Independence: The Nadew Command, an Ethiopian army corps in Eritrea, is attacked on three sides by military units of the Eritrean People's Liberation Front in the opening action of the Battle of Afabet.

The Eritrean War of Independence was an armed conflict and insurgency aimed at achieving self-determination and independence for Eritrea from Ethiopian rule. Starting in 1961, Eritrean insurgents engaged in guerrilla warfare to liberate Eritrea Province from the control of the Ethiopian Empire under Haile Selassie and later the Derg under Mengistu. Their efforts ultimately succeeded in 1991 with the fall of the Derg regime.

The Eritrean People's Liberation Front (EPLF), colloquially known as Shabia, was an armed Marxist–Leninist organization that fought for the independence of Eritrea from Ethiopia. It emerged in 1973 as a far-left to left-wing nationalist group that split from the Eritrean Liberation Front (ELF). After achieving Eritrean independence in 1991, it transformed into the People's Front for Democracy and Justice (PFDJ), which serves as Eritrea's sole legal political party.
