One of the most well know civil rights fighters was Malcolm X. Malcolm X was into the rapid change of how African Americans were treated. He didn't want a gradual change he wanted a change that could be seen right away. He wanted all of the racist people in the world to see that African Americans were the same as everyone else. He wanted this "by any means necessary".

Malcolm X's style was welcomed by alot of people but also feared by alot of people. They feared that if the African American population pushed that the forced that was to be pushed back would be greater and more severe.
