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 )
