The PRM was organized in four sectors, industrial labor, peasants, a middle class sector (composed largely of government workers), and the military. This organization was a resurrection of corporatism, essentially organization by estates or interest groups. Each sector of the party had a parallel organization, so that the labor sector was composed of the Confederation of Mexican Workers (CTM), the peasant sector by the National Confederation of Campesinos, (CNC); and the middle class sector by the Federation of Unions of Workers in Service to the State (FSTSE), created in 1938. The old Federal Army had been destroyed in the Revolution and the post-revolutionary military had increasingly been transformed from a collection of veteran revolutionary fighters into a military organized along more traditional lines of hierarchy and control.
