It is a branch of feminist theory that developed out of a need to define the complexities Indigenous women face as a result of the intersections of race, ethnicity, and gender.  Indigenous feminism has grown from postcolonial feminism as it acknowledges the devastating consequences of colonization on Indigenous peoples, and the importance of decolonization in dismantling oppressive systems.  Indigenous feminism may go by other (geographically specific) names such as: Native American feminism and Tribal feminism in the United States and Canada, or Aboriginal feminism in Australia, but each of these regionally-adapted terms fall under the broad rubric of Indigenous feminism.
