1917年，各黨各派終於形成共識，製定憲法，進入民主憲政時期。今天的墨西哥已從一黨專政進入政黨政治，經濟穩定成長。不過，身處美洲交通中樞的地位，一直是毒品轉運重鎮，除了造成嚴重的社會問題之外，也影響其國際形象。查緝毒品成為當今政府的重要工作。
The Mexican Revolution
1910-1921
In 1910 the 80-year-old Díaz decided to hold an election to serve another term as president. He thought he had long since eliminated any serious opposition in Mexico; however, Francisco I. Madero, an academic from a rich family, decided to run against him and quickly gathered popular support, despite Díaz's putting Madero in jail.
When the official election results were announced, it was declared that Díaz had won re-election almost unanimously, with Madero receiving only a few hundred votes in the entire country. This fraud by the Porfiriato was too blatant for the public to swallow, and riots broke out. Madero prepared a document known as the Plan de San Luis Potosí, in which he called the Mexican people to take their weapons and fight against the government of Porfirio Díaz on November 20, 1910. Madero managed to flee to San Antonio, Texas, where he started to prepare his overthrow of the Díaz government. This started what is known as the Mexican Revolution.
The Federal Army was defeated by the revolutionary forces which were led by, amongst others, Emiliano Zapata in the South, Pancho Villa and Pascual Orozco in the North, and Venustiano Carranza. Porfirio Díaz resigned in 1911 for the "sake of the peace of the nation" and went to exile in France, where he died in 1915.

The revolutionary leaders had many different objectives; revolutionary figures varied from liberals such as Madero to radicals such as Emiliano Zapata and Pancho Villa. As a consequence, it proved very difficult to reach agreement on how to organize the government that emanated from the triumphant revolutionary groups. The result of this was a struggle for the control of Mexico's government in a conflict that lasted more than twenty years. This period of struggle is usually referred to as part of the Mexican Revolution, although it might also be considered a civil war. Presidents Francisco I. Madero (1913), Venustiano Carranza (1920), and former revolutionary leaders Emiliano Zapata (1919) and Pancho Villa (1923) were assassinated during this time, amongst many others.
Following the resignation of Díaz and a brief reactionary interlude, Madero was elected President in 1911. He was ousted and killed in 1913 by Victoriano Huerta, with the support of the U.S. ambassador to Mexico, Henry Lane Wilson, but not that of U.S. President-elect Woodrow Wilson. Huerta was a former General of Porfirio Díaz. Huerta's brutality soon lost him his domestic support, and his regime was actively opposed by the Wilson Administration. In 1915 he was overthrown by Venustiano Carranza, a former revolutionary general. Carranza promulgated a new Constitution on February 5, 1917. The Mexican Constitution of 1917 still guides Mexico. Carranza was assassinated in an internal feud of his former supporters over who would replace him as President.
In 1920 Álvaro Obregón, one of Carranza's former allies who plotted against him, became president. He accommodated all elements of Mexican society except the most reactionary clergy and landlords, and successfully catalyzed social liberalization, particularly in curbing the role of the Catholic Church, improving education and taking steps toward instituting women's civil rights.
While the Mexican revolution and civil war may have subsided after 1920, armed conflicts did not cease. The most widespread conflict of this era was the battle between those favoring a secular society with separation of Church and State and those favoring supremacy of the Roman Catholic Church, which developed into an armed uprising by supporters of the Church that came to be called "la Guerra Cristera."
It is estimated that between 1910 and 1921 about 900,000 people died.
The Cristero War 1926-1929
Between 1926 and 1929 an armed conflict in the form of a popular uprising broke out against the anti-Catholic anti-clerical Mexican government, set off specifically by the anti-clerical provisions of the Mexican Constitution of 1917. Discontent over the provisions had been simmering for years. The conflict is known as the Cristero War. A number of articles of the 1917 Constitution were at issue. Article 5 outlawed monastic religious orders. Article 24 forbade public worship outside of church buildings, while Article 27 restricted religious organizations' rights to own property. Finally, Article 130 took away basic civil rights of members of the clergy: priests and religious leaders were prevented from wearing their habits, were denied the right to vote, and were not permitted to comment on public affairs in the press.
The Cristero War was eventually resolved diplomatically, largely with the influence of the U.S. Ambassador. The conflict claimed the lives of some 90,000: 56,882 on the federal side, 30,000 Cristeros, and numerous civilians and Cristeros who were killed in anticlerical raids after the war's end. As promised in the diplomatic resolution, the laws considered offensive to the Cristeros remained on the books, but no organized federal attempts to enforce them were put into action. Nonetheless, in several localities, persecution of Catholic priests continued based on local officials' interpretations of the law.
The Institutional Revolutionary Party
In 1929, the National Mexican Party (PNM) was formed by the serving president, General Plutarco Elías Calles. (It would later become the Partido Revolucionario Institucional (PRI) that ruled the country for the rest of the 20th century.) The PNM succeeded in convincing most of the remaining revolutionary generals to dissolve their personal armies to create the Mexican Army, and so its foundation is considered by some the real end of the Mexican Revolution.
The PRI set up a new type of system, led by a caudillo.
The PRI is typically referred to as the three-legged stool, in reference to Mexican workers, peasants and bureaucrats.
After it was founded in 1929, the PRI monopolized all the political branches. The PRI did not lose a senate seat until 1988 or a gubernatorial race until 1989. It wasn't until July 2, 2000, that Vicente Fox of the opposition "Alliance for Change" coalition, headed by the National Action Party (PAN), was elected president. His victory ended the Institutional Revolutionary Party's 71-year hold on the presidency.
President Lázaro Cárdenas
President Lázaro Cárdenas came to power in 1934 and transformed Mexico. On April 1, 1936 he exiled Calles, the last general with dictatorial ambitions, thereby removing the army from power.
Cárdenas managed to unite the different forces in the PRI and set the rules that allowed his party to rule unchallenged for decades to come without internal fights. He nationalized the oil industry on March 18, 1938, the electricity industry, created the National Polytechnic Institute, granted asylum to Spanish expatriates fleeing the Spanish Civil War, started land reform and the distribution of free textbooks for children.
President Manuel Ávila Camacho
Manuel Ávila Camacho, Cárdenas's successor, presided over a "bridge" between the revolutionary era and the era of machine politics under PRI that would last until 2000. Ávila, moving away from nationalistic autarchy, proposed to create a favorable climate for international investment, favored nearly two generations earlier by Madero. Ávila's regime froze wages, repressed strikes, and persecuted dissidents with a law prohibiting the "crime of social dissolution." During this period, the PRI regime thus betrayed the legacy of land reform. Miguel Alemán Valdés, Ávila's successor, even had Article 27 amended to protect elite landowners.
