The black power movement of the 1960's was much different than the goals set out by Martin Luther King Jr. Instead of focusing on integration, the black power movement focused on gaining power in political society without the help of white citizens. Members of this movement, like Malcolm X, felt that whenever white citizens got involved in marches or nonviolent protest, it weakened the movement.
Also, instead of nonviolent disobedience, members of the black power movement were in favor of self-defense. They felt that black citizens had the right to fight back if prompted with a violent situation or physical abuse.
