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.
Liberal Party (Mexico)
When Mexico achieved its independence in 1821, the Mexican political life was altered by constant struggles between Liberals and Conservatives. The Liberal Party enacted the Federal Constitution of 1857, which along with the Plan of Ayutla (1854) and other liberal reforms polarized Mexican society to lead the Reform War (1857–1861), the Second French Intervention in México (1862–1867) and the Second Mexican Empire (1863–1867).
