Mexican Revolution, (1910–20), a long and bloody struggle among several factions in constantly shifting alliances which resulted ultimately in the end of the 30-year dictatorship in Mexico and the establishment of a constitutional republic. The revolution began against a background of widespread dissatisfaction with the elitist and oligarchical policies of Porfirio Díaz that favoured wealthy landowners and industrialists. When Díaz in 1908 said that he welcomed the democratization of Mexican political life and appeared ambivalent about running for his seventh reelection as president in 1910, Francisco Madero emerged as the leader of the Antireeleccionistas and announced his candidacy. Díaz had him arrested and declared himself the winner after a mock election in June, but Madero, released from prison, published his Plan de San Luis Potosí from San Antonio, Texas, calling for a revolt on November 20. The revolt was a failure, but it kindled revolutionary hope in many quarters. In the north, Pascual Orozco and Pancho Villa mobilized their ragged armies and began raiding government garrisons. In the south, Emiliano Zapata waged a bloody campaign against the local caciques (rural political bosses). In the spring of 1911 the revolutionary forces took Ciudad Juárez, forced Díaz to resign, and declared Madero president.
Madero’s regime faltered from the start. Zapata turned against him, angered at his failure to effect the immediate restoration of land to dispossessed Indians. Orozco, initially a supporter of Madero, was also dissatisfied with the slow pace of reform under the new government and led a revolutionary movement in the north. The U.S. government then turned against Madero as well, fearing that the new president was too conciliatory to the rebel groups and concerned about the threat that civil war in Mexico was posing to American business interests there. Tensions reached a peak when yet another faction of rebel forces, led by Félix Díaz (the former dictator’s nephew), clashed with federal troops in Mexico City under the command of Victoriano Huerta. On Feb. 18, 1913, after the ninth day of that melee (known as La Decena Trágica, or “The Ten Tragic Days”), Huerta and Díaz met in the office of U.S. Ambassador Henry Lane Wilson and signed the so-called “Pact of the Embassy,” in which they agreed to conspire against Madero and to install Huerta as president. Huerta assumed the presidency the following day, after arresting Madero, who was assassinated a few days later.
Opposition to Huerta’s drunken and despotic rule grew in the north, and an uneasy alliance was formed between Pancho Villa, álvaro Obregón, and Venustiano Carranza, whose Plan de Guadalupe called for Huerta’s resignation. In the spring and summer of 1914, the rebel forces converged on Mexico City, forcing Huerta into exile. Carranza declared himself president on August 20, over Villa’s objections. A state of anarchy and bloodshed ensued until Villa, Obregón, and Zapata held a convention at which it was agreed that the rivalry between Villa and Carranza made order impossible, and they elected Eulalio Gutiérrez interim president. Villa retained the support of Zapata and backed Gutiérrez. Obregón, however, re-allied himself with Carranza and routed Villa in a bloody battle in April 1915 at Celaya. Thereafter, both Zapata and Villa lost ground, and Villa, blaming his defeat on U.S. Pres. Woodrow Wilson’s support of Carranza, launched a vendetta against Americans in Mexico and in U.S. border towns. He executed about 17 U.S. citizens at Santa Isabel in January 1916, and his raid on Columbus, New Mexico, two months later, which claimed the lives of some 17 Americans, prompted Pres. Woodrow Wilson to order Gen. John J. Pershing into the Mexican hills in futile pursuit.
Carranza, president again, presided over the writing of the constitution of 1917, which conferred dictatorial powers on the president but gave the government the right to confiscate land from wealthy landowners, guaranteed workers’ rights, and limited the rights of the Roman Catholic Church. Carranza remained in power by eliminating those who opposed him (Zapata was assassinated in 1919), but in 1920 opposition reached a climax when he tried to break up a railroad strike in Sonora. Deserted by virtually all his supporters, including Obregón, he was killed attempting to flee the capital on May 21. Adolfo de la Huerta became interim president until Obregón was elected in November.
Many historians regard 1920 as the end of the revolution, but sporadic violence and clashes between federal troops and various rebel forces continued until the reformist president, Lázaro Cárdenas, took office in 1934 and institutionalized the reforms that were fought for during the revolution and were legitimized in the constitution of 1917.
