El Teatro Campesino (The Farmworkers' Theater) was founded by Luis Valdez and Agustin Lira in 1965 as the cultural wing of the United Farm Workers (UFW) as a result of the Great Delano Grape Strike in 1965. All of the actors were farmworkers and involved in organizing for farmworkers' rights. Its first performances sought to recruit members for the UFW and dissuade strikebreakers. Many early performances were not scripted and were rather conceived through the direction of Valdez and others through "actos", in which a scenario would be proposed for a scene and then dialogue would simply be improvised.
