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.
Conservative Party (Mexico)
The Conservative Party was a Mexican political party that sought to preserve the organization and colonial Spanish values, both in government and in society. Although as a party it was founded in 1849, after the defeat of Mexico in the war with the United States, most of the political ideology directly descended from the Jesuits expelled in the 18th century, and the establishment of a Criollism or Hispanism sentiment, which then emerged and were strongly influenced by conservative European thoughts. It also advocated the preservation and supremacy of the Criollos élite culture (Mexicans of full Spanish ancestry) over those of mestizo or indigenous. It was a party of the élite, established by white landowners and aristocrats. The Conservative Party disappeared in 1867, after the fall of Maximilian I of Mexico.
