The Federation of Parties of the Mexican People (Spanish: Federación de Partidos del Pueblo Mexicano) was a federation of socialist political parties that existed from 1945 to 1954.
The alliance was founded by Genovevo de la O, a former Zapatista commander, in 1945.
The FPPM drew most of its support from left wing academics and soldiers who had grown disillusioned with the almost omnipotent Institutional Revolutionary Party (PRI) and believed the PRI no longer represented the ideas of the Mexican Revolution.
Notable members of the FPPM were Marcelino García Barragán [es], Rubén Jaramillo, Francisco J. Múgica, José C. Valadés [es] and Miguel Henríquez Guzmán.
Henríquez claimed to have been victorious, but the official result showed PRI candidate Adolfo Ruiz Cortines to be the winner.
