Who first used the phrase black power?

The phrase "Black Power" was first popularized by civil rights activist Stokely Carmichael during a speech in 1966 at a rally in Greenwood, Mississippi. Carmichael used it to articulate a call for racial dignity, self-reliance, and empowerment for African Americans. The term quickly became a rallying cry for the broader Black Power movement, which sought to address systemic racism and promote social justice.
