Why did Luis Valdez make the song La Bamba?

Luis Valdez did not actually create the song "La Bamba"; it is a traditional Mexican folk song that originated in Veracruz. Valdez, however, is known for his contributions to the Chicano Civil Rights Movement and for popularizing the song through the 1987 film "La Bamba," which tells the story of rock and roll star Ritchie Valens. In the film, Valdez aimed to celebrate Mexican-American culture and highlight Valens' impact on music. The song itself serves as a symbol of cultural identity and pride.
