Álvaro Obregón Tapia was a Mexican political figure who served as governor of the northwestern border state of Sonora from 1955 to 1961. He was a son of Álvaro Obregón Salido and María Tapia Monteverde. Obregón Tapia's father was a brilliant Sonoran general in the Mexican Revolution, who became president of Mexico in 1920, re-elected in 1928, but assassinated before he could take office. Obregón Tapia's birth in 1916 was after his father's defeat of Pancho Villa in 1915 in the Battle of Celaya, a decisive victory for the Constitutionalists.
