The
Mexican Revolution is a broad term for political and social changes in the early 20th century. Most scholars consider it to span the years 1910–1920, from
Francisco I. Madero's call for armed rebellion in the
Plan of San Luis Potosí until the election of General
Álvaro Obregón in December 1920. Foreign powers had important economic and strategic interests in the outcome of power struggles in Mexico, with
the United States' participation in the Mexican Revolution playing an especially significant role. The Revolution grew increasingly broad-based, radical, and violent. Revolutionaries sought far-reaching social and economic reforms by strengthening the state and weakening the conservative forces of the Church, rich landowners, and foreign capitalists. Some scholars consider the promulgation of the
Mexican Constitution of 1917 as the revolution's endpoint. "Economic and social conditions improved under revolutionary policies, so that the new society took shape within a framework of official revolutionary institutions," with the Constitution providing that framework. Organized labor gained significant power, as seen in Article 123 of the Constitution of 1917.
Land reform in Mexico was enabled by Article 27.
Economic nationalism was also enabled by Article 27, restricting ownership of enterprises by foreigners. The Constitution restricted the
Catholic Church in Mexico; implementing the restrictions in the late 1920s resulted in the
Cristero War. The Constitution and practice enshrined a ban on the president's re-election. Political succession was achieved in 1929 by creating the
Partido Nacional Revolucionario (PNR). This party dominated Mexico's politics for the remainder of the 20th century, now called the
Institutional Revolutionary Party. One major effect of the revolution was the disappearance of the
Federal Army in 1914, defeated by revolutionary forces of the various
factions in the Mexican Revolution. The Mexican Revolution was based on popular participation. At first, it was based on the peasantry who demanded land, water, and a more representative national government. Wasserman finds that: Popular participation in the revolution and its aftermath took three forms. First, everyday people, though often in conjunction with elite neighbors, generated local issues such as access to land, taxes, and village autonomy. Second, the popular classes provided soldiers to fight in the revolution. Third, local issues advocated by campesinos and workers framed national discourses on land reform, the role of religion, and many other questions.
Election of 1910 and popular rebellion Porfirio Díaz announced in an interview with a US journalist
James Creelman that he would not run for president in 1910. This set off a spate of political activity by potential candidates, including
Francisco I. Madero, a member of one of Mexico's richest families. Madero was part of the Anti-Reelectionist Party, whose main platform was the end of the Díaz regime. But Díaz reversed his decision to retire and ran again. He created the office of vice president, which could have been a mechanism to ease the presidential transition. But Díaz chose a politically unpalatable running mate,
Ramón Corral, over a popular military man,
Bernardo Reyes, and a popular civilian
Francisco I. Madero. He sent Reyes on a "study mission" to Europe and jailed Madero. Official election results declared that Díaz had won almost unanimously, and Madero received only a few hundred votes. This fraud was too blatant, and riots broke out. Uprisings against Díaz occurred in the fall of 1910, particularly in Mexico's North and the southern state of
Morelos. Helping unite opposition forces was a political plan drafted by Madero, the
Plan of San Luis Potosí, in which he called on the Mexican people to take up arms and fight against the Díaz government. The rising was set for November 20, 1910. Madero escaped from prison to
San Antonio, Texas, where he began preparing to overthrow Díaz—an action today considered the start of the
Mexican Revolution. Díaz tried to use the Army to suppress the revolts, but Revolutionary forces—led by, among others,
Emiliano Zapata in the South,
Pancho Villa and
Pascual Orozco in the North, and
Venustiano Carranza—defeated the
Federal Army. Díaz resigned in May 1911 for the "sake of the nation's peace." The terms of his resignation were spelled out in the
Treaty of Ciudad Juárez, but it also called for an interim presidency and new elections to be held.
Francisco León de la Barra served as interim president. The Federal Army, although defeated by the northern revolutionaries, was kept intact.
Francisco I. Madero, whose 1910
Plan of San Luis Potosí had helped mobilize forces opposed to Díaz, accepted the political settlement. He campaigned in the
presidential elections of October 1911, won decisively, and was inaugurated in November 1911.
Madero presidency and its opposition, 1911–1913 Following the resignation of Díaz, Madero was elected president in 1911. The revolutionary leaders had many different objectives; revolutionary figures varied from liberals such as Madero to radicals such as
Emiliano Zapata and
Pancho Villa. Consequently, it proved impossible to agree on how to organize the government that emerged from the triumphant first phase of the revolution. This standoff over political principles quickly led to a struggle for government control, a violent conflict that lasted more than ten years.
Counter-revolution and Civil War, 1913–1915 , ruler of Mexico from 1913 to 1914 Madero was ousted and killed in February 1913 during a coup d'état now known as the
Ten Tragic Days. General
Victoriano Huerta, one of Díaz's former generals and a nephew of Díaz,
Félix Díaz, plotted with the US ambassador to Mexico,
Henry Lane Wilson, to topple Madero and reassert the policies of Díaz. Within a month of the coup, rebellions started spreading in Mexico, most prominently by the governor of the state of Coahuila,
Venustiano Carranza, along with old revolutionaries demobilized by Madero, such as
Pancho Villa. The northern revolutionaries fought under the name of the
Constitutionalist Army, with Carranza as the "First Chief" (
primer jefe). In the South,
Emiliano Zapata continued his rebellion in Morelos under the
Plan of Ayala, calling for the expropriation of land and redistribution to peasants. Huerta offered peace to Zapata, who rejected it. Huerta convinced
Pascual Orozco, whom he fought while serving the Madero government, to join Huerta's forces. Supporting the Huerta regime were business interests in Mexico, both foreign and domestic; landed elites; the Catholic Church; and the German and British governments. The
Federal Army became an arm of the Huerta regime, swelling to 200,000 men, many pressed into service and most ill-trained. The US did not recognize the Huerta government. Still, from February to August 1913, it imposed an arms embargo on exports to Mexico, exempting the Huerta government and favoring the regime against emerging revolutionary forces. However, President
Woodrow Wilson sent a special envoy to Mexico to assess the situation, and reports on the many rebellions in Mexico convinced Wilson that Huerta was unable to maintain order. Arms ceased to flow to Huerta's government, which benefited the revolutionary cause. at the entrance of Ojinaga The US Navy made an incursion on the Gulf Coast, occupying
Veracruz in April 1914. Although Mexico was engaged in a civil war at the time, the US intervention united Mexican forces in their opposition to the US. Foreign powers helped broker US withdrawal in the
Niagara Falls peace conference. The US timed its pullout to support the Constitutionalist faction under Carranza. Initially, the forces in northern Mexico were united under the Constitutionalist banner, with able revolutionary generals serving the civilian First Chief Carranza in the
Plan of Guadalupe. Pancho Villa began to split from supporting Carranza as Huerta was on his way out, primarily because Carranza was politically too conservative for Villa. Carranza, a rich hacienda owner whose interests were threatened by Villa's more radical ideas, opposed land reform. Zapata in the South was also hostile to Carranza due to his stance on land reform. In July 1914, Huerta resigned under pressure and went into exile. His resignation marked the end of an era since the
Federal Army, a repeatedly ineffective fighting force against the revolutionaries, ceased to exist. With the exit of Huerta, the revolutionary factions decided to meet and make "a last-ditch effort to avert more intense warfare than that which unseated Huerta." Called to meet in Mexico City in October 1914, revolutionaries opposed to Carranza's influence successfully moved the venue to Aguascalientes. The
Convention of Aguascalientes did not reconcile the various victorious
factions in the Mexican Revolution but was a brief pause in revolutionary violence. The break between Carranza and Villa became definitive during the convention. Rather than First Chief Carranza being named president of Mexico, General
Eulalio Gutiérrez was chosen. Carranza and Obregón left Aguascalientes with far smaller forces than Villa's. The convention declared Carranza in rebellion against it, and civil war resumed, this time between revolutionary armies that had fought for a united cause to oust Huerta. of the American
10th Cavalry Regiment taken prisoner during the
Battle of Carrizal, Mexico in 1916. Villa went into alliance with Zapata to form the Army of the convention. Their forces separately moved on to the capital and captured Mexico City in 1914, which Carranza's forces had abandoned. The famous picture of Villa, sitting in the presidential chair in the National Palace, and Zapata is a classic image of the Revolution. Villa reportedly told Zapata that "the presidential chair is too big for us." The alliance between Villa and Zapata did not function in practice beyond this initial victory against the Constitutionalists. Zapata returned to his southern stronghold in Morelos, where he engaged in guerrilla warfare under the Plan of Ayala. The two rival armies of Villa and Obregón met on April 6–15, 1915, in the
Battle of Celaya. The shrewd, modern military tactics of Obregón met the frontal cavalry charges of Villa's forces. The Constitutionalist victory resulted in Carranza emerging as the political leader of Mexico. Villa retreated north, seemingly into political oblivion. Carranza and the Constitutionalists consolidated their position, with only Zapata opposing them until his assassination in 1919.
Constitutionalists in power, 1915–1920 in
La Cañada, Querétaro, January 22, 1916. Venustiano Carranza promulgated a new constitution on February 5, 1917. The
Mexican Constitution of 1917, with significant amendments in the 1990s, still governs Mexico. On 19 January 1917, a secret message (the
Zimmermann Telegram) was sent from the German foreign minister to Mexico proposing joint military action against the United States if war broke out. The offer included material aid to Mexico to reclaim the territory lost during the
Mexican–American War. Zimmermann's message was intercepted and published, causing outrage in the US and catalyzing
an American declaration of war against Germany in early April. Carranza then formally rejected the offer, and the threat of war with the US eased. Carranza was assassinated in 1920 during an internal feud among his former supporters over who would replace him as president. ==Consolidation of revolution, 1920–1940==
