Dolores Huerta, a co-founder of the United Farmworkers union, has died at the age of 96. Her family announced her passing on Wednesday.

Huerta was a prominent labor leader and feminist activist in the U.S. She played a key role in the Chicano movement and was instrumental in organizing farm workers. Her work focused on improving conditions for agricultural laborers, many of whom were Mexican-American.

Born in 1925, Huerta became a leading voice in the fight for workers' rights. She co-founded the United Farm Workers with César Chávez in the 1960s. Her activism included strikes and boycotts that brought national attention to the plight of farm workers. Huerta also worked on broader civil rights issues, advocating for gender equality and racial justice.

Huerta’s legacy is marked by her unwavering commitment to social justice. She received numerous awards for her contributions, including the Presidential Medal of Freedom. Her death marks the end of an era for labor and civil rights movements in the U.S.
