Mexican Revolution
The Mexican Revolution (, 1910–1920) was a major revolution that included a sequence of armed struggles that transformed Mexican culture and government. Although the regime of President Porfirio Díaz was increasingly unpopular after 31 years, there was no foreboding that a revolution was about to break out in 1910. The regime failed to find a controlled solution to the issue of presidential succession, resulting in a power struggle among competing elites, and elites and the middle classes that sometimes involved the "masses". This provided the opportunity in some places for agrarian [[insurrection]]. Although often studied as an event solely of Mexican history, "From the beginning to the end, foreign activities figured crucially in the Revolution's course, not simple antagonism from the U.S. government, but complicated Euro-American imperialist rivalries, extremely intricate during the first world war."
