Raíces de sangre[2][3] (Spanish pronunciation: [raˈises de ˈsaŋɡɾe]) (Roots of Blood) is a Mexican movie written and directed by Jesús Salvador Treviño released in 1978 in Mexico and other countries.

Amidst a heightening labor tension and attempts at organizing the workers, a deadly riot occurs.

[7] In 1983, professor of Chicano/Latino Studies Dr. Alejandro Morales reviewed and analyzed the literature of three of Treviño's major 1970s works, stating about Raíces de sangre that it is "an antidote to Hollywood productions such as Boulevard Nights and Walk Proud, which focus on stereotypical images of Chicano gangs".

"[8]: 128  Morales further notes the symbolism of the fence dividing the border, and the Chicanos and the Mexicans, at the end of the film and observes that "...the criminals go unpunished and not even an educated Harvard lawyer will change the exploitative conditions that exist on the border.

[9] In his 2014 book, Latino Image Makers in Hollywood, author Frank Javier Garcia Berumen describes Treviño's Raíces de sangre as foundational to Chicano cinema.
