Prior to Italian colonization in 1885, what is now Eritrea had been ruled by the various local or international powers that successively dominated the Red Sea region. In 1896, the Italians used Eritrea as a springboard for their disastrous attempt to conquer Ethiopia. Eritrea was placed under British military administration after the Italian surrender in World War II. In 1952, a UN resolution federating Eritrea with Ethiopia went into effect. The resolution ignored Eritrean pleas for independence but guaranteed Eritreans some democratic rights and a measure of autonomy. Almost immediately after the federation went into effect, however, these rights began to be abridged or violated.
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 independence struggle was led by the Eritrean Liberation Front (ELF). In 1970, members of the group had a falling out, and a group broke away from the ELF and formed 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, and Isaias Afwerki had emerged as its leader. Much of the materiel used to combat Ethiopia was captured from the Ethiopian Army.
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 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--began to advance 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. These talks were attended by the four major combatant groups, including the EPLF.
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 support for Mengistu cooled their ardor. 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.
ISAIAS Afwerki has been Eritrea's only president since independence; his rule, particularly since 2001, has been highly autocratic and repressive. His government has created a highly militarized society by pursuing an unpopular program of mandatory conscription into national service – divided between military and civilian service – of indefinite length. A two-and-a-half-year border war with Ethiopia that erupted in 1998 ended under UN auspices in December 2000. A subsequent 2007 Eritrea-Ethiopia Boundary Commission (EEBC) demarcation was rejected by Ethiopia. More than a decade of a tense “no peace, no war” stalemate ended in 2018 after the newly elected Ethiopian prime minister accepted the EEBC’s 2007 ruling, and the two countries signed declarations of peace and friendship. Following the July 2018 peace agreement with Ethiopia, Eritrean leaders engaged in intensive diplomacy around the Horn of Africa, bolstering regional peace, security, and cooperation, as well as brokering rapprochements between governments and opposition groups. In November 2018, the UN Security Council lifted an arms embargo that had been imposed on Eritrea since 2009, after the UN Somalia-Eritrea Monitoring Group reported they had not found evidence of Eritrean support in recent years for Al-Shabaab. The country’s rapprochement with Ethiopia has led to a steady resumption of economic ties, with increased air transport, trade, tourism, and port activities, but the economy remains agriculture-dependent, and Eritrea is still one of Africa’s poorest nations. Despite the country's improved relations with its neighbors, ISAIAS has not let up on repression and conscription and militarization continue.
