The Mayan civilization flourished throughout much of Guatemala and the surrounding region long before the Spanish arrived, but it was already in decline when the Mayans were defeated by Pedro de Alvarado in 1523-24. During Spanish colonial rule, most of Central America came under the control of the Captaincy General of Guatemala.

The first colonial capital, Ciudad Vieja, was ruined by floods and an earthquake in 1542. Survivors founded Antigua, the second capital, in 1543. In the 17th century, Antigua became one of the richest capitals in the New World. Always vulnerable to volcanic eruptions, floods, and earthquakes, Antigua was destroyed by two earthquakes in 1773, but the remnants of its Spanish colonial architecture have been preserved as a national monument. The third capital, Guatemala City, was founded in 1776, after Antigua was abandoned.

Guatemala gained independence from Spain on September 15, 1821; it briefly became part of the Mexican Empire and then for a period belonged to a federation called the United Provinces of Central America. From the mid-19th century until the mid-1980s, the country passed through a series of dictatorships, insurgencies (particularly beginning in the 1960s), coups, and stretches of military rule with only occasional periods of representative government.

In 1944, Gen. Jorge Ubico's dictatorship was overthrown by the "October Revolutionaries," a group of dissident military officers, students, and liberal professionals. A civilian president, Juan Jose Arevalo, was elected in 1945 and held the presidency until 1951. Social reforms initiated by Arevalo were continued by his successor, Col. Jacobo Arbenz. Arbenz permitted the communist Guatemalan Labor Party to gain legal status in 1952. By the mid-point of Arbenz's term, communists controlled key peasant organizations, labor unions, and the governing political party, holding some key government positions. Despite most Guatemalans' attachment to the original ideals of the 1944 uprising, some private sector leaders and the military viewed Arbenz's policies as a menace. The army refused to defend the Arbenz government when a U.S.-backed group led by Col. Carlos Castillo Armas invaded the country from Honduras in 1954 and quickly took over the government.

In response to the increasingly autocratic rule of Gen. Ydigoras Fuentes, who took power in 1958 following the murder of Colonel Castillo Armas, a group of junior military officers revolted in 1960. When they failed, several went into hiding and established close ties with Cuba. This group became the nucleus of the forces that were in armed insurrection against the government for the next 36 years.

Four principal left-wing guerrilla groups--the Guerrilla Army of the Poor (EGP), the Revolutionary Organization of Armed People (ORPA), the Rebel Armed Forces (FAR), and the Guatemalan Labor Party (PGT)--conducted economic sabotage and targeted government installations and members of government security forces in armed attacks. These organizations combined to form the Guatemalan National Revolutionary Unity (URNG) in1982. At the same time, extreme right-wing groups of self-appointed vigilantes, including the Secret Anti-Communist Army (ESA) and the White Hand, tortured and murdered students, professionals, and peasants suspected of involvement in leftist activities.

Shortly after President Julio Cesar Mendez Montenegro took office in 1966, the army launched a major counterinsurgency campaign that largely broke up the guerrilla movement in the countryside. The guerrillas then concentrated their attacks in Guatemala City, where they assassinated many leading figures, including U.S. Ambassador John Gordon Mein in 1968. Between 1966 and 1982, there were a series of military or military-dominated governments.

On March 23, 1982, army troops commanded by junior officers staged a coup to prevent the assumption of power by Gen. Angel Anibal Guevara, the hand-picked candidate of outgoing president and Gen. Romeo Lucas Garcia. They denounced Guevara's electoral victory as fraudulent. The coup leaders asked retired Gen. Efrain Rios Montt to negotiate the departure of Lucas and Guevara. Rios Montt had been the candidate of the Christian Democracy Party in the 1974 presidential elections and was widely regarded as having been denied his own victory through fraud.

Rios Montt was by this time a lay pastor in the evangelical protestant "Church of the Word." In his inaugural address, he stated that his presidency resulted from the will of God. He formed a three-member military junta that annulled the 1965 constitution, dissolved Congress, suspended political parties, and canceled the electoral law. After a few months, Rios Montt dismissed his junta colleagues and assumed the de facto title of "President of the Republic."

Guerrilla forces and their leftist allies denounced Rios Montt. Rios Montt sought to defeat the guerrillas with military actions and economic reforms; in his words, "rifles and beans." In May 1982, the Conference of Catholic Bishops accused Rios Montt of responsibility for growing militarization of the country and for continuing military massacres of civilians. General Rios Montt was quoted in the New York Times of July 18, 1982 as telling an audience of indigenous Guatemalans, "If you are with us, we'll feed you; if not, we'll kill you."

The government began to form local civilian defense patrols (PACs). Participation was in theory voluntary, but in practice, many Guatemalans, especially in the heavily indigenous northwest, had no choice but to join either the PACs or the guerrillas. Rios Montt's conscript army and PACs recaptured essentially all guerrilla territory--guerrilla activity lessened and was largely limited to hit-and-run operations. However, Rios Montt won this partial victory at an enormous cost in civilian deaths.

Rios Montt's brief presidency was probably the most violent period of the 36-year internal conflict, which resulted in about 200,000 deaths of mostly unarmed indigenous civilians. Although leftist guerrillas and right-wing death squads also engaged in summary executions, forced disappearances, and torture of noncombatants, the vast majority of human rights violations were carried out by the Guatemalan military and the PACs they controlled. The internal conflict is described in great detail in the reports of the Historical Clarification Commission (CEH) and the Archbishop's Office for Human Rights (ODHAG). The CEH estimates that government forces were responsible for 93% of the violations; ODHAG earlier estimated that government forces were responsible for 80%.

On August 8, 1983, Rios Montt was deposed by his own Minister of Defense, Gen. Oscar Humberto Mejia Victores, who succeeded him as de facto president of Guatemala. Mejia justified his coup, saying that "religious fanatics" were abusing their positions in the government and also because of "official corruption." Seven people were killed in the coup, although Rios Montt survived to found a political party (the Guatemalan Republic Front) and to be elected President of Congress in 1995 and 2000. Awareness in the United States of the conflict in Guatemala, and its ethnic dimension, increased with the 1983 publication of I, Rigoberta Menchu, An Indian Woman in Guatemala.

General Mejia allowed a managed return to democracy in Guatemala, starting with a July 1, 1984 election for a Constituent Assembly to draft a democratic constitution. On May 30, 1985, after 9 months of debate, the Constituent Assembly finished drafting a new constitution, which took effect immediately. Vinicio Cerezo, a civilian politician and the presidential candidate of the Christian Democracy Party, won the first election held under the new constitution with almost 70% of the vote, and took office on January 14, 1986.
