Crips

The Crips are a primarily African-American alliance of street gangs that are based in the coastal regions of Southern California. Founded in Los Angeles, California, in 1969, mainly by Raymond Washington and Stanley Williams, the Crips began as an alliance between two autonomous gangs, and developed into a loosely connected network of individual "sets", often engaged in open warfare with one another. Its members have traditionally worn blue clothing since around 1973.
