The Crips are a gang based in the coastal regions of southern California. They were founded in Los Angeles, California in 1969 mainly by Raymond Washington and Stanley Williams. Once a single alliance between two autonomous gangs, they are now a loosely connected network of individual "sets", often engaged in open warfare with one another. Its members traditionally wear blue clothing, a practice that has waned somewhat due to police crackdowns specifically targeting gang members. Historically, members have been primarily of African-American heritage.
The Crips are one of the largest and most violent associations of street gangs in the United States. With an estimated 30,000 to 35,000 members in 2008, they have been involved in murders, robberies and drug dealing, among other crimes.
The Crips have a long and bitter rivalry with the Bloods.
