The Nationalist Revolutionary Movement of the People ( Movimiento Nacionalista Revolucionario del Pueblo , MNRP) was founded in April 1965 by Jaime Arellano Castañeda following a split in the Revolutionary Nationalist Movement. The objective of the Nationalist Revolutionary Movement of the People was to fight the right-wing military dictatorship of General René Barrientos Ortuño. The MNRP took part in elections in 1966 backing Mario Díez de Medina and in 1978 backing Jaime Arellano Castañeda.
