. "The Maximato was a period in the historical and political development of Mexico ranging from 1928 to 1934. That period was named after Plutarco El\u00EDas Calles, who was known as the Jefe M\u00E1ximo of the Mexican Revolution. El\u00EDas Calles was president in the period 1924-1928, but throughout the next six years, Calles was the de facto leader of Mexico. There were three presidents in this era, all of them subordinate to a lesser or greater extent to Calles."@en .
