Long ago, Mexico went through a big change. A leader named Porfirio Díaz ruled for a long time. Many people were not happy with his rules. They wanted more land and fair ways to work. 

The Mexican Revolution was a long period of fighting. It lasted from 1910 to 1920. Before the war, Porfirio Díaz ruled Mexico for many years. He helped build railroads and factories. However, many people were unhappy. Wealthy families owned most of the land. Many poor farmers had no land at all. 
In 1910, Francisco Madero ran for president. Díaz jailed him, so Madero called for an uprising. This started the war. Díaz left the country in 1911. Madero became president, but he faced more fighting. A leader named Emiliano Zapata fought for land reform. 
Fighting continued as new leaders took power. One group was called the Constitutionalists. They were led by Venustiano Carranza. In 1917, they made a new Constitution. This set of rules gave rights to workers. It also helped farmers get land. 
The Mexican Revolution was a major series of conflicts in Mexico. It lasted from November 20, 1910, to December 1, 1920. Many people call it the most important event in modern Mexican history. 
Before the war, President Porfirio Díaz ruled Mexico for a long time. He held power from 1876 until 1911. 
In 1910, a man named Francisco I. Madero challenged Díaz in an election. Díaz jailed Madero to stop him from winning. In response, Madero called for an armed uprising. This was known as the Plan of San Luis Potosí. Rebellions started in Morelos and then spread to northern Mexico. The Federal Army was too weak to stop the rebels. Because of this, Díaz resigned in May 1911 and left the country. Madero was then elected as the new President in November 1911.
Even after Díaz left, the fighting did not stop. 

Eventually, the Constitutionalist faction won the battles. 
The Mexican Revolution was an extended sequence of armed regional conflicts. It lasted from November 20, 1910, to December 1, 1920. Many historians call it the defining event of modern Mexican history. 
Before the revolution, President Porfirio Díaz ruled Mexico for many years. He held the presidency from 1876 until 1911. This era is known as the Porfiriato. 
Political tension grew because Díaz controlled the government with a strong hand. He often rigged elections to stay in power. He also used a rural police force called the Rurales to seize land. This force was directly under his control. In 1910, Francisco I. Madero challenged Díaz in the presidential election. Díaz responded by jailing Madero. In protest, Madero issued the Plan of San Luis Potosí. This plan called for an armed uprising against the regime. Rebellions began in Morelos and spread heavily through northern Mexico. The Federal Army proved unable to suppress these widespread uprisings. This weakness forced Díaz to resign in May 1911. He went into exile, and an interim government took over.
After Díaz left, Madero was elected President in November 1911. However, his government was fragile and inexperienced. He immediately faced an armed rebellion from Emiliano Zapata in Morelos. 
This coalition was known as the Constitutionalist Army. It was led by Venustiano Carranza, the Governor of Coahuila. 

In February 1917, Carranza promulgated a new Constitution for Mexico. 
From 1920 to 1940, a group of revolutionary generals held the presidency. They established a period of centralized state power. During these decades, the military was brought under civilian control. A political party was founded in 1929. This group eventually became the Institutional Revolutionary Party, or the PRI. The PRI ruled Mexico until the year 2000. Even though the revolution ended years ago, its impact remains. The struggle for democracy and land rights continues to shape Mexican identity. The transition of power in 2000 was seen by some as a continuation of the democratic goals started in 1910.
