Maximato

thumb|Plutarco Elías Calles, called the jefe máximo. He was seen as the de facto leader of Mexico during the Maximato.

The Maximato was a transitional period in the historical and political development of Mexico from 1 December 1928 to 1 December 1934. Named after former president Plutarco Elías Calles's sobriquet el Jefe Máximo (the maximum leader), the Maximato was the period in which Calles continued to exercise power and exert influence without holding the presidency. The six-year period was the term that President-elect Alvaro Obregón would have served if he had not been assassinated immediately after the July 1928 elections.
