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.
1929 Mexican general election
The National Revolutionary Party, founded in 1928 by Mexico's most powerful leader at the time, Plutarco Elías Calles, made its debut in these elections. The 1929 elections marked the beginning of 71 uninterrupted years of rule by that party, which was later renamed Party of the Mexican Revolution in 1938 and finally, Institutional Revolutionary Party (PRI) in 1946. No opposition party would win a Presidential election until the 2000 elections.
