Institutional Revolutionary Party
The Institutional Revolutionary Party (, PRI) is a Mexican political party founded in 1929 that held uninterrupted power in the country for 71 years from 1929 to 2000, first as the National Revolutionary Party (, PNR), then as the Party of the Mexican Revolution (, PRM), and finally renaming itself as the Institutional Revolutionary Party in 1946.
Party of the Poor (Mexico)
After the collapse of the Party of the Poor following Cabaña's death, some remnants of it joined together with the militant Revolutionary Clandestine Workers' Union Party of the People (PROCUP, formed in 1971), which followed a doctrine that combined traditional Marxist-Leninist and Maoist concepts, achieving "ideological unification" and forming the PROCUP-PdlP by 1980. The group would continue carrying out small armed operations, including assassinations and bombings, throughout the 1980s and early 1990s. In 1985, a group calling itself the Party of the Poor kidnapped the Unified Socialist Party of Mexico politician Arnoldo Martinez Verdugo. David Cabañas Barrientos, Lucio's brother, became a principal PROCUP-PdlP leader, and was imprisoned in 1990 for his alleged role in an assassination. The movement dissolved in 1996, merging with new militant groups such as the "Ejército Popular Revolucionario" and the "Ejército Revolucionario del Pueblo Insurgente".
