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.
Confederation of Mexican Workers
The Confederation of Mexican Workers ("Confederación de Trabajadores de México" (CTM)) is the largest confederation of labor unions in Mexico. For many years, it was one of the essential pillars of the Partido Revolucionario Institucional (the Institutional Revolutionary Party, or PRI), which ruled Mexico for more than seventy years. However, the CTM began to lose influence within the PRI structure in the late 1980s, as technocrats increasingly held power within the party. Eventually, the union found itself forced to deal with a new party in power after the PRI lost the 2000 general election, an event that drastically reduced the CTM's influence in Mexican politics.
