why did black and chicano movements decide to create their own separate branches of the Women's Rights movement

Black and Chicano movements wanted to fight for their rights as their voices were not heard.

Explanation:

They were inspired by the white feminist movement in America.

The Chicano movement, like the black movement, fought for civil rights. The Chicano movement centred on the inequalities encountered by Mexican Americans in the United States. Both movement began in the 1960s and 1970s against racism, unemployment, and discrimination.

Black and Chicano movements fight against gender inequality in America. The two movements shared similarities in their economic and educational reforms while embracing their cultures and identities.
