The Rollin 30s Original Harlem Crips were originally known as Harlem Godfathers during the early 1970s. Their history makes them one of the oldest Crip sets on the westide of Los Angeles.
Beginning from the Jefferson Park area of Los Angeles, the Rollin 30′s consist of the Avenues, Denker Park, 35th, 37th, and 39th street clicks. The oldest members come from Denker Park, 39th Street and Avenues. The 35th and 37th Street clicks emerged during the mid 1990′s.
Their main rivals are the Rollin 20s Bloods to the north. Their secondary Blood rival are the Black P Stones Bloods to the west who are located in the Jungles. They have been engaged in the rivalry with the 20s Bloods since the late 1970s but they have also have been feuding with the Rollin 40s Crips to the north since approximately 1996 but that feud has diminished since 2006.
Their territory is about 2.04 square miles between Jefferson (north) and King Blvd (south) and Crenshaw (west) and Normandie (east). A portion of their turf extends further east to Vermont between Exposition (north) and King Blvd (south). They have the second largest turf of all black gangs in Los Angeles, slightly smaller than the turf of the Eight Trey Gangsters Crips.
A history of this neighborhood was published in Issue #3 of Allhood Magazine in 2007.
