Álvaro Obregón Salido was a Sonoran-born general in the Mexican Revolution. He became the 46th President of Mexico from 1920 to 1924 and assassinated in 1928 as President-elect. In the mythology of the Revolution, "Alvaro Obregón stood out as the organizer, the peacemaker, the unifier." He joined the Revolution after the February 1913 coup d'etat against Francisco I. Madero that brought General Victoriano Huerta to the presidency. Obregón supported Sonora's decision to follow Governor of Coahuila Venustiano Carranza as leader of the northern revolutionary coalition, the Constitutionalist Army, against the Huerta regime. Obregón rose quickly in the ranks and became, along with revolutionary general Francisco Villa, the Constitutionalist Army's best general. Carranza appointed Obregón commander of the revolutionary forces in northwestern Mexico. When the Constitutionalists defeated Huerta in July 1914, Villa broke with Carranza, while Obregón remained loyal to him. In the civil war of the winners, between Carranza and Obregón on one side and Villa and peasant leader Emiliano Zapata on the other, Obregón decisively defeated Villa's army in 1915.
