May 1, 1926 - Efraín Ríos Montt

José Efraín Ríos Montt (Spanish: [efɾaˈin ˈrios ˈmont]; 16 June 1926 – 1 April 2018) was a Guatemalan military officer who served as de facto President of Guatemala from 1982 to 1983. His brief tenure as chief executive was one of the bloodiest periods in the long-running Guatemalan Civil War.

Ríos Montt was a career army officer. He was director of the Guatemalan military academy and rose to the rank of brigadier general. He was briefly chief of staff of the Guatemalan army in 1973. However, he was soon forced out of the position over differences with the military high command. He ran for president in the 1974 general election, losing to the official candidate, General Kjell Laugerud, in an electoral process widely regarded as fraudulent.
