Plutarco Elías Calles (25 September 1877 – 19 October 1945) was a general in the Mexican Revolution and a Sonoran politician, serving as President of Mexico from 1924 to 1928. The 1924 Calles presidential campaign was the first populist presidential campaign in Mexico's history, as he called for land redistribution and promised equal justice, expanded education, further labor rights, and democratic governance. After Calles' populist phase (1924–1926) he was committed to separating church from state (1926–1928), passing several anticlerical laws that resulted in the Cristero War.
