Guatemala, 1954 — military coup

Guatemala (GTM)Central America, AmericasJune 27, 1954

Event Summary

President Jacobo Árbenz of Guatemala (1951–54), whose nationalistic economic and social reforms alienated conservative landowners, the army, and the U.S. government, was forced to resign on 27 June 1954 and go into exile.

The CIA had helped organize a counterrevolutionary army of exiles led by Col. Carlos Castillo Armas, who soon became president and reversed most of the reforms of the previous decade, offering generous concessions to foreign investors.
