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.
Party of the Poor (Mexico)
The Party of the Poor was founded in 1967 in the Mexican state of Guerrero as a political organization. This took place in the context of the Dirty War's first beginnings, a conflict between the Institutional Revolutionary Party government and various urban and rural left-wing movements which would last roughly between the Tlatelolco massacre in October 1968 and the late 1970s, and a long period of social unrest in the country. In terms of armed conflict the PdlP was preceded by groups like the People's Guerrilla Group (1963–1965).
