On May 21, 1920, Mexican President Venustiano Carranza was executed by army generals after fleeing an armed rebellion in Mexico.
"Venustiano Carranza Garza (December 29, 1859–May 21, 1920) was a Mexican politician, warlord, and general. Before the Mexican Revolution (1910–1920) he served as mayor of Cuatro Ciénegas and as a congressman and senator. When the Revolution broke out, he initially allied himself with Francisco Madero's faction and independently raised his own army when Madero was assassinated. Carranza was president of Mexico from 1917–1920 but was unable to keep a lid on the chaos that had plagued his country since 1910. He was assassinated in Tlaxcalantongo in 1920 by troops led by General Rodolfo Herrero."
