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
After several decades in power the PRI had become a symbol of corruption and electoral fraud. The conservative National Action Party (PAN) became a stronger party after 1976 when it obtained the support from businessmen after recurring economic crises. Consequently, the PRI's left wing separated and formed its own party, the Party of the Democratic Revolution (PRD) in 1989.
