The flowering of black nationalism in the mid to late 1960s is usually presented as an evolutionary process. In fact, a vision of global class revolution led by oppressed people of color was not an outgrowth of the civil rights movements failure but existed alongside its main ideas. The break between what's considered to be the good liberal movement and the bad nationalist movement often begins with the Watts rebellion in 1965. It's ironic because it's not like the Watts rebellion was a nationalist insurgency.
