The Federal Army in Mexico had long been an interventionist force in Mexican politics, with notable generals becoming Presidents of Mexico. After the
War of the Reform and the successful ouster of
the French empire in Mexico in 1867, the soldiers who defeated them were adherents of the
liberalism. General
Porfirio Díaz rose through the ranks without formal military training, and was a hero of the
Battle of Puebla on 5 May 1862. He came to power by coup in 1876, ousting the civilian President
Sebastián Lerdo. Díaz knew the power and the danger of a strong military and once he became President of Mexico, he sought to curtail the power of the generals, who held provincial power and were not under control of the central government. It took him "nearly fifteen years to achieve full military control." He did so by a combination of bribes and other economic lures for those he could not confront militarily. He divided Mexico into eleven military zones, whose boundaries did not correspond to state boundaries. To prevent collusion between the state governors, whom he appointed, and military commanders, he rotated commanders on a regular basis so that they could not build a local power base. By a variety of means, he reduced the officer corps by 500, including 25 generals. Díaz also sought to professionalize the army. He moved the
Mexican Military Academy back to
Chapultepec Castle, the Presidential residence. In 1847, cadets at the academy resisted the
invading U.S. forces, in their deaths called the
Niños Héroes, but the academy was relocated and lost prestige. Díaz revived it, with cadets to be sons of "good families" (code for "white"). They were taught the arts of modern warfare. By 1900, some 9,000 graduates were officers in the Federal Army. Military training prepared cadets for war with foreign invaders, when the reality was the army dealt with internal order, along with the
rural police force. By early 1900, the majority of generals in the military were not trained at the military academy, but had participated in the war against the French, that had ended some 35 years previously. The generals were old. The Federal Army was overstaffed, with far more officers commanding too few recruits, with 9,000 officers and ostensibly 25,000 enlisted men. Many who were counted as enlisted men did not exist, but were on the muster rolls because the officers received a stipend to provide food for their men. Officers pocketed the difference between the 25,000 enrolled and the 18,000 or so who actually served. Díaz had initially said that he would not run in the 1910 presidential elections. A rich hacienda owner from Coahuila,
Francisco I. Madero, published a book entitled
The Presidential Succession of 1910, excoriating militarism in Mexico and calling for democracy. Madero's ideal was civilian rule. Only when it became more than clear that Díaz would remain in power by any means did Madero call for an armed rebellion against him in the 1910
Plan of San Luis Potosí. Minor rebellions broke out on the 20 November 1910 date he set, which the Federal Army suppressed. But more a more serious rebellion in Chihuahua led by
Pascual Orozco and
Pancho Villa demonstrated the weakness of the Federal forces, surprising the rebels. More rebellions in various parts of Mexico broke out, forcing Díaz to resign in May 1911. "Considering the small number of battles actually fought, [the rebel] triumph was more directly attributable to the weakness of the
federales than to the strength of the Ejército Libertador." ==Under Madero, 1911–1913==
