Álvaro Obregón

Born in Navojoa, Sonora, Obregón joined the Revolution after the February 1913 coup d'état that brought General Victoriano Huerta to the presidency. Obregón supported Sonora's decision to follow Governor Venustiano Carranza as leader of the northern revolutionary coalition, the Constitutionalist Army, against the Huerta regime. Obregón quickly became the Constitutionalist Army's most prominent general, along with Pancho Villa. Carranza appointed Obregón commander of the revolutionary forces in northwestern Mexico. The Constitutionalists defeated Huerta in July 1914, and the Federal Army dissolved in August. In 1915, the revolution entered a new phase of civil war between the Conventionists led by Emiliano Zapata and Villa versus Obregón and Carranza. Obregón was made leader of the Constitutionalist army and defeated Villa, but lost his right arm. In 1917, the Constitution of Mexico went into effect and the Conventionists forces were quickly getting defeated by Obregón and the Constitutionalist Army. Carranza stepped down from the presidency and designated Ignacio Bonillas to succeed him. Obregón and other Sonoran generals Plutarco Elías Calles and Adolfo de la Huerta ousted Bonillas and Carranza under the Plan of Agua Prieta. Obregón was elected to the presidency in 1920 with overwhelming popular support.
Obregón's presidency saw educational reform, the flourishing of Mexican muralism, moderate land reform, and labor laws sponsored by the increasingly powerful Regional Confederation of Mexican Workers. In August 1923, he signed the Bucareli Treaty that clarified the rights of the Mexican government and U.S. oil interests and brought U.S. diplomatic recognition to his government. In 1923–24, Obregón's finance minister, Adolfo de la Huerta, launched a rebellion when Obregón designated Plutarco Elías Calles as his successor. De la Huerta garnered support by many revolutionaries who were opposed to Obregón's apparent emulation of Porfirio Díaz's example. Obregón returned to the battlefield and defeated the rebellion. In his victory, he was aided by the United States with arms and planes that bombed de la Huerta's supporters.
In 1924, Obregón's fellow Northern revolutionary general and hand-picked successor, Plutarco Elías Calles, was elected president. Although Obregón ostensibly retired to Sonora, he remained influential under Calles. Calles pushed through constitutional reform to again make re-election possible, but not continuously. Obregón won the 1928 election. Before beginning his second term however, he was assassinated by José de León Toral during the Cristero War. Obregón's political legacy is that of pragmatic centrism, allying with various factions of the revolution to accomplish his goals, with one historian describing him as "Alvaro Obregón stood out as the organizer, the peacemaker, the unifier." His assassination precipitated a political crisis in the country, ultimately leading to Calles founding the National Revolutionary Party, later renamed the Institutional Revolutionary Party, which would dominate Mexican politics throughout the 20th century.
