Calles Expelled — End of the Maximato

President Cárdenas ordered Plutarco Elías Calles expelled from Mexico and deported to the United States, ending the 'Maximato' period in which Calles controlled three puppet presidents (1928–1936). The expulsion demonstrated Cárdenas's political strength and transformed the PNR from Calles's instrument into the state's organizational arm. It was the decisive consolidation of presidential authority over the party.
