Mexican Revolution
A decade-long civil war that reshaped Mexican government and society.
The Mexican Revolution, known in Spanish as the Revolución mexicana, was a series of armed regional conflicts that stretched from November 20, 1910, to December 1, 1920. Often described as the most significant event in Mexico’s modern history, it dismantled the Federal Army, replaced it with revolutionary forces, and reshaped the country’s government and culture. The northern Constitutionalists won on the battlefield and wrote the current Mexican Constitution, which sought to strengthen the central government. Revolutionary generals then held power from 1920 to 1940. While mainly a civil war, foreign nations with economic and strategic stakes in Mexico influenced the outcome, with the United States playing a particularly large role. Around one million people died, most of them non-combatants.
President Porfirio Díaz had ruled for decades, from 1876 to 1911, but his regime grew increasingly unpopular. Still, no one in 1910 expected a revolution. The aging Díaz couldn’t manage a controlled presidential succession, sparking a power struggle among elites and the middle class during a time of intense labor unrest, including the Cananea and Río Blanco strikes. Wealthy northern landowner Francisco I. Madero ran against Díaz in the 1910 election, but Díaz jailed him. Madero then called for an armed uprising through the Plan of San Luis Potosí. Rebellions began in Morelos, just south of the capital, and then spread more widely across northern Mexico. The Federal Army failed to stop the uprisings, exposing its weakness and encouraging rebels. Díaz resigned in May 1911 and went into exile. An interim government took over until elections, kept the Federal Army, and demobilized revolutionary forces. This first phase was relatively short and bloodless.
Madero won the presidency and took office in November 1911. He soon faced an armed rebellion from Emiliano Zapata in Morelos, where peasants demanded quick land reform. Politically inexperienced, Madero led a fragile government, and more regional revolts broke out. In February 1913, top army generals from Díaz’s era staged a coup in Mexico City, forcing Madero and Vice President Pino Suárez to resign. Days later, both were killed on orders from the new president, Victoriano Huerta. This sparked a bloodier phase of the Revolution. A coalition of northerners opposed to Huerta, called the Constitutionalist Army and led by Coahuila’s governor Venustiano Carranza, joined the fight. Zapata’s forces kept rebelling in Morelos. Huerta’s regime lasted from February 1913 to July 1914, when revolutionary armies defeated the Federal Army. Then the revolutionary groups turned on each other. Carranza’s Constitutionalists beat the army of former ally Francisco “Pancho” Villa by the summer of 1915.
Carranza consolidated power, and a new constitution was issued in February 1917. The Mexican Constitution of 1917 gave all men the right to vote, promoted secularism, workers’ rights, economic nationalism, and land reform, and boosted federal government authority. Carranza became president in 1917, serving until 1920. He tried to force a civilian successor, which led northern revolutionary generals to rebel. Carranza fled Mexico City and was killed. From 1920 to 1940, revolutionary generals served as president, each finishing their terms except from 1928 to 1934. During this time, state power grew more centralized, revolutionary reforms were carried out, and the military was brought under civilian control. The Revolution was a decade-long civil war that produced new political leaders who gained power and legitimacy from their roles in the conflict. The political party they founded in 1929 later became the Institutional Revolutionary Party (PRI), which ruled Mexico until the 2000 presidential election. The Revolution’s end is not clearly defined. Even the conservative winner of the 2000 election, Vicente Fox, claimed his victory was the heir to Madero’s 1910 democratic election, linking himself to the Revolution’s heritage and legitimacy.

Lore & Background
The decades-long regime of President Porfirio Díaz (1876–1911) was increasingly unpopular, but there was no foreboding in 1910 that a revolution was about to break out. The aging Díaz failed to find a controlled solution to presidential succession, resulting in a power struggle among competing elites and the middle classes, which occurred during a period of intense labor unrest, exemplified by the Cananea and Río Blanco strikes. When wealthy northern landowner Francisco I. Madero challenged Díaz in the 1910 presidential election and Díaz jailed him, Madero called for an armed uprising against Díaz in the Plan of San Luis Potosí. Rebellions broke out first in Morelos (immediately south of the nation's capital city) and then to a much greater extent in northern Mexico. The Federal Army could not suppress the widespread uprisings, showing the military's weakness and encouraging the rebels. Díaz resigned in May 1911 and went into exile, an interim government was installed until elections could be held, the Federal Army was retained, and revolutionary forces demobilized. The first phase of the Revolution was relatively bloodless and short-lived. Madero was elected President, taking office in November 1911. He immediately faced the armed rebellion of Emiliano Zapata in Morelos, where peasants demanded rapid action on agrarian reform. Politically inexperienced, Madero's government was fragile, and further regional rebellions broke out. In February 1913, prominent army generals from the former Díaz regime staged a coup d'etat in Mexico City, forcing Madero and Vice President Pino Suárez to resign. Days later, both men were assassinated by orders of the new president, Victoriano Huerta. This initiated a new and bloody phase of the Revolution, as a coalition of northerners opposed to the counter-revolutionary regime of Huerta, the Constitutionalist Army led by the Governor of Coahuila Venustiano Carranza, entered the conflict. Zapata's forces continued their armed rebellion in Morelos. Huerta's regime lasted from February 1913 to July 1914, and the Federal Army was defeated by revolutionary armies. The revolutionary armies then fought each other, with the Constitutionalist faction under Carranza defeating the army of former ally Francisco "Pancho" Villa by the summer of 1915. Carranza consolidated power and a new constitution was promulgated in February 1917. The Mexican Constitution of 1917 established universal male suffrage, promoted secularism, workers' rights, economic nationalism, and land reform, and enhanced the power of the federal government. Carranza became President of Mexico in 1917, serving a term ending in 1920. He attempted to impose a civilian successor, prompting northern revolutionary generals to rebel. Carranza fled Mexico City and was killed. From 1920 to 1940, revolutionary generals held the office of president, each completing their terms (except from 1928-1934). This was a period when state power became more centralized, and revolutionary reform implemented, bringing the military under the civilian government's control. The Revolution was a decade-long civil war, with new political leadership that gained power and legitimacy through their participation in revolutionary conflicts. The political party those leaders founded in 1929, which would become the Institutional Revolutionary Party (PRI), ruled Mexico until the presidential election of 2000. When the Revolution ended is not well defined, and even the conservative winner of the 2000 election, Vicente Fox, contended his election was heir to the 1910 democratic election of Francisco Madero, thereby claiming the heritage and legitimacy of the Revolution.
Reader's Guide
The Mexican Revolution is significant as the defining event of modern Mexican history, leading to the destruction of the Federal Army and its replacement by a revolutionary army. The northern Constitutionalist faction, led by Venustiano Carranza, prevailed and drafted the Mexican Constitution of 1917, which established universal male suffrage, promoted secularism, workers' rights, economic nationalism, and land reform, and enhanced the power of the federal government.

The political party founded in 1929, which became the Institutional Revolutionary Party (PRI), ruled Mexico until the presidential election of 2000. The conflict resulted in the deaths of around one million people, mostly non-combatants, and involved significant foreign, especially U.S., intervention. The revolution's end is not well defined, and even the conservative winner of the 2000 election claimed its heritage and legitimacy.
