What movement did Cesar Chavez help organize?

Cesar Chavez played a crucial role in organizing the United Farm Workers (UFW), which was instrumental in advocating for the rights and better working conditions of farm laborers, particularly migrant workers in California. The UFW focused on issues such as fair wages, labor rights, and safe working environments.

Chavez co-founded the union in 1962, and his leadership was marked by significant actions like the Delano grape strike, which brought national attention to the struggles of agricultural workers. The UFW became a symbol of the labor movement and helped to elevate the voices of a marginalized group within society.

While the Civil Rights Movement was a broader social movement that included various struggles for racial equality, and the Labor Party focused on political representation for labor interests, neither directly pertains to the agricultural workers’ specific issues that Chavez championed. The Gold Rush Movement, on the other hand, was a historical event from the mid-1800s unrelated to Chavez's work. Thus, the United Farm Workers is the correct organization that encapsulates the essence of Chavez's efforts in labor activism.
