In the 1960's many African Americans and black leaders rejected integration and non-violence in favor of<em> separatism and aggression.</em> Many were concerned about the cost of the peaceful approach - many injuries and deaths, without really resolving the segregation in the north of the country, concentrating on the southern part only.
A movement called <em>Black Muslims </em>emerged, with Malcolm X as its spokesman, demanding a separate, black only nation in the USA. This movement thought non-violence meant non-defense, thus admitting to racial segregation.

He was a French soldier who helped teach the American soldiers at Valley forge. He was incredible influential with teaching necessary techniques to win the war
