The Mexican Revolution (Spanish: Revolución mexicana) was a major armed struggle ca. 1910–20 that radically transformed Mexican politics and society. Although recent research has focused on local and regional aspects of the Revolution, it was a "genuinely national revolution."The failure of the 35-year long regime of Porfirio Díaz to find a managed solution to the presidential succession meant there was a political crisis among competing elites and the opportunity for agrarian insurrection.
