It was the Black Panther party that changed from nonviolent to Black Power confrontational ideologies after the Watts Riots of 1964. They believed passive resistance wasn't enough.
The Black Panther Party was an African American revolutionary party, established in 1966 in Oakland, California, by Huey Newton and Bobby Seale. The gathering's unique reason for existing was to watch African American neighborhoods to shield occupants from demonstrations of police severity.
The Panthers in the long run formed into a Marxist progressive gathering that required the furnishing of every single African American, the exception of African Americans from the draft and from all assets of purported white America, the arrival of every African American from prison, and the payment of compensation to African Americans for a considerable length of time of exploitation by white Americans.
