Consolidating power, President Carranza had peasant-leader Emiliano Zapata assassinated in 1919.  Carranza had gained support of the peasantry during the Revolution, but once in power he did little to distribute land, and, in fact, returned some confiscated land to their original owners. President Carranza's best general, Obregón, served briefly in Carranza's administration, but returned to his home state of Sonora to position himself to run in the 1920 presidential election. Carranza chose a political and revolutionary no-body to succeed him. Obregón and two other Sonoran revolutionary generals drew up the Plan of Agua Prieta, overthrowing Carranza, who died fleeing Mexico City in 1920. General Adolfo de la Huerta became interim president, followed the election of General Álvaro Obregón.
