Alvaro Obregón Salido (February 19, 1880 - July 17, 1928) was a Mexican farmer, warlord and general. He was one of the key players in the Mexican Revolution (1910-1920) and it is his election as President in 1920 that is considered by many as the ending point of the Revolution, although the violence continued afterwards. A brilliant and charismatic general, his rise to power is contributed to his effectiveness, ruthlessness, and the fact that he was the only one of the Revolution's “Big Four” still standing after 1923, as Pancho Villa, Emiliano Zapata and Venustiano Carranza all were assassinated.
