Answer:
The military dictatorship of Carlos Castillo Armas was installed, backed by the US Central Intelligence Agency, and was followed by a series of military dictators, and short after the Guatemalan Civil War began in 1960
Step-by-step explanation:
The Guatemalan Revolution began in 1944, after overthrowing the military dictatorship of Jorge Ubico, and giving way to the country's first democratic election. But the US government didn't like the Guatemalan Revolution, as they saw the new democratic government as Communist, and in August 1953, US President Dwight Eisenhower authorized the CIA to perform operation PBSUCCESS, which trained and armed 480 men lead by Carlos Castillo Armas, who then invaded Guatemala on June 18 1954, and with the fear of a US invasion , the Guatemalan army refused to fight. This event strengthened a widespread anti-US sentiment in Latin America. This tense climate lead to the beginning of the Guatemalan Civil War in 1960, after a failed attempt to overthrow President Miguel Ydígoras Fuentes. The Civil War was fought between the Government of Guatemala and various leftist rebel groups supported by ethnic Maya indigenous groups and Ladino peasants. The first Guerrilla group was formed in 1962, the MR13 (Revolutionary movement November 13) which remained active until 1971. The Civil War ended on December 29, 1996, during the presidency of Alvaro Arzú, after the signing of a peace treaty between the Government of Guatemala, and the URNG (Guatemalan National Revolutionary Unity)
