In 1962, Emperor Haile Sellassie unilaterally dissolved the Eritrean parliament and annexed the country, sparking the Eritrean fight for independence from Ethiopia that continued after Haile Sellassie was ousted in a coup in 1974. The new Ethiopian Government, called the Derg, was a Marxist military junta led by strongman Mengistu Haile Miriam.

During the 1960s, the Eritrean Liberation Front (ELF) led the Eritrean independence struggle. In 1970, some members of the group broke away to form the Eritrean People's Liberation Front (EPLF). By the late 1970s, the EPLF had become the dominant armed Eritrean group fighting against the Ethiopian Government, with Isaias Afwerki as its leader. The EPLF used material captured from the Ethiopian Army to fight against the government.

By 1977, the EPLF was poised to drive the Ethiopians out of Eritrea. That same year, however, a massive airlift of Soviet arms to Ethiopia enabled the Ethiopian Army to regain the initiative and forced the EPLF to retreat to the bush. Between 1978 and 1986, the Derg launched eight major offensives against the independence movement--all of which failed. In 1988, the EPLF captured Afabet, headquarters of the Ethiopian Army in northeastern Eritrea, prompting the Ethiopian Army to withdraw from its garrisons in Eritrea's western lowlands. EPLF fighters then moved into position around Keren, Eritrea's second-largest city. Meanwhile, other dissident movements were making headway throughout Ethiopia. At the end of the 1980s, the Soviet Union informed Mengistu that it would not be renewing its defense and cooperation agreement. With the withdrawal of Soviet support and supplies, the Ethiopian Army's morale plummeted, and the EPLF--along with other Ethiopian rebel forces--advanced on Ethiopian positions.

The United States played a facilitative role in the peace talks in Washington during the months leading up to the May 1991 fall of the Mengistu regime. In mid-May, Mengistu resigned as head of the Ethiopian Government and went into exile in Zimbabwe, leaving a caretaker government in Addis Ababa. Later that month, the United States chaired talks in London to formalize the end of the war. The four major combatant groups, including the EPLF, attended these talks.

Having defeated the Ethiopian forces in Eritrea, EPLF troops took control of their homeland. In May 1991, the EPLF established the Provisional Government of Eritrea (PGE) to administer Eritrean affairs until a referendum could be held on independence and a permanent government established. EPLF leader Isaias became the head of the PGE, and the EPLF Central Committee served as its legislative body.

A high-level U.S. delegation was present in Addis Ababa for the July 1-5, 1991 conference that established a transitional government in Ethiopia. The EPLF attended the July conference as an observer and held talks with the new transitional government regarding Eritrea's relationship to Ethiopia. The outcome of those talks was an agreement in which the Ethiopians recognized the right of the Eritreans to hold a referendum on independence.

Although some EPLF cadres at one time espoused a Marxist ideology, Soviet assistance for Mengistu limited the level of Eritrean interest in seeking Soviet support. The fall of communist regimes in the former Soviet Union and the Eastern Bloc convinced them it was a failed system. The EPLF (and later its successor, the PFDJ) expressed its commitment to establishing a democratic form of government and a free-market economy in Eritrea. The United States agreed to provide assistance to both Ethiopia and Eritrea, conditional on continued progress toward democracy and human rights.

On April 23-25, 1993, Eritreans voted overwhelmingly for independence from Ethiopia in a UN-monitored free and fair referendum. The Eritrean authorities declared Eritrea an independent state on April 27, and Eritrea officially celebrated its independence on May 24, 1993.
