Institutional Revolutionary Party
Cárdenas's successor Manuel Ávila Camacho gave the party its present name in 1946. The party, under its three different names, held every political position until 1946 when the PAN started winning posts for municipal president and federal deputies and senators, starting in 1946, after the party changed its name to its current name, the Institutional Revolutionary Party. By then, the party had acquired a reputation for corruption, and while this was admitted (to a degree) by some of its affiliates, its supporters maintained that the role of the party was crucial in the modernization and stabilization of Mexico.
Institutional Revolutionary Party
Even though the armed phase of the Mexican Revolution had ended in 1920, Mexico continued to encounter political unrest. A grave political crisis caused by the 1928 assassination of president-elect Álvaro Obregón led to the founding in 1929 of the National Revolutionary Party (, PNR) by Plutarco Elías Calles, Mexico's president from 1924 to 1928.
