Guatemala, 1946 — military coup attempt

Guatemala (GTM)Central America, AmericasJune 26, 1946

Event Summary

On 26 June 1946 military conspirators attempted a coup against President Juan Jose Arevalo of Guatemala, one of the earliest of the roughly twenty five coup attempts he survived during his 1945 to 1951 presidency. Arevalo, a reformist elected with 85 percent of the vote in Guatemala's first democratic election after the 1944 revolution that toppled the Ubico dictatorship, faced constant plotting from conservative military officers who had grown powerful under Ubico, from right-wing politicians, and from clergy and landowners alarmed by his labor reforms and his constitution's provisions on property. The June 1946 attempt failed like nearly all the others, the armed forces majority and the mobilized public standing by the elected government.

Arevalo completed his full term and handed power to Jacobo Arbenz after the 1950 election, the first transfer between democratically elected leaders in Guatemalan history.

Editorial Note

The 26 June 1946 attempt is one of the many largely undocumented individual plots within the well attested count of about 25 against Arevalo; sources here establish the pattern, the plotter profile, and the outcome. Links forward to the Arana 1949 attempt and the 1954 Arbenz overthrow already treated in the dataset.

Cross-Reference
