By 1966, the civil rights movement had been gaining momentum for more than a decade, as thousands of African Americans embraced a strategy of nonviolent protest against racial segregation and demanded equal rights under the law.

But for an increasing number of African Americans, particularly young black men and women, that strategy did not go far enough. Protesting segregation, they believed, failed to adequately address the poverty and powerlessness that generations of systemic discrimination and racism had imposed on so many black Americans.

Inspired by the principles of racial pride, autonomy and self-determination expressed by Malcolm X (whose assassination in 1965 had brought even more attention to his ideas), as well as liberation movements in Africa, Asia and Latin America, the Black Power movement that flourished in the late 1960s and ‘70s argued that black Americans should focus on creating economic, social and political power of their own, rather than seek integration into white-dominated society.

Crucially, Black Power advocates, particularly more militant groups like the Black Panther Party, did not discount the use of violence, but embraced Malcolm X’s challenge to pursue freedom, equality and justice “by any means necessary.”
