In short: Beginning in 1961, Eritrean insurgents launched a protracted war to secure independence from Ethiopia. Over three decades, the conflict evolved from a regional insurgency into a complex geopolitical theater involving Cold War superpowers, shifting alliances, and brutal counterinsurgency campaigns, ultimately culminating in the birth of a sovereign nation in 1993.

The roots of the conflict trace back to the post-World War II era. After Italian colonial rule ended in 1941, the United Nations federated Eritrea with Ethiopia in 1952, intending to balance Ethiopian sovereignty with Eritrean autonomy. However, this arrangement collapsed in 1962 when Emperor Haile Selassie unilaterally dissolved the federation and annexed Eritrea. This act triggered the Eritrean Liberation Front (ELF) to escalate its armed struggle, which had begun in September 1961 under Hamid Idris Awate.

The war intensified following the 1974 Ethiopian Revolution, which replaced the monarchy with the Marxist-Leninist Derg regime led by Mengistu Haile Mariam. The Derg initially attempted to pacify the region with brute force, including massacres in both Muslim and Christian areas. By 1977, the Eritrean People's Liberation Front (EPLF) had emerged as the dominant insurgent force, often clashing with the ELF in a bitter civil war. The conflict saw massive military offensives, such as the 1982 Red Star Campaign, where Ethiopia deployed over 80,000 troops and utilized air power and toxic gas against EPLF positions.

International involvement defined the war's trajectory. The United States supported the Ethiopian monarchy in the 1960s, while the Soviet Union and Cuba later provided critical military aid to the Derg. Conversely, various Arab nations and the Palestine Liberation Organization supported the Eritrean rebels. The tide turned in the late 1980s as Soviet support evaporated and Ethiopian morale plummeted. In May 1991, the EPLF decisively defeated Ethiopian forces in Eritrea, while the Ethiopian People's Revolutionary Democratic Front captured Addis Ababa. Following a 1993 referendum where the Eritrean people voted almost unanimously for independence, the nation finally achieved formal international recognition.
