The Westside Crips were a street gang composed in the early 1970s in the area, which had as borders the following:
•Western Avenue to The West
•Normandie Avenue to The East
•Imperial Highway to The South
•103rd to The North
Denker Avenue was a sultry spot for The Westside Crips and was referred to as The 100s, considering it was passing through 103rd to 113th, being the heart of the gang, alongside another sultry spot, albeit mostly considered 105th, 106th, and 107th's hangout, Holly Park on the corner of 107th and Western Avenue.
Following a murder case in which Westside Crips were trialed and convicted, back in 1973, just outside of The Superdome in Long Beach, inner beef rose in "The 100s" due to the member's personal ties within the gang. Everyone took each member's part on who was directly accountable for it, and the tensions have escalated to the point of No Return.
What was known as The Westside Crips have scattered in sets such as:
•W/S Underground ( Original ) Blocc Crips
•W/S 107 Original Blocc Crips
•W/S 113 Original Blocc Crips.
The point of No Return wasn't violence, but a complex breakdown of a powerful gang into sets with ties that stood still strong to each other.
Following the point of No Return, the "Rollin 100s" alliance was formed and consisted of:
•W/S Underground ( Original ) Blocc Crips
•W/S 107 Original Blocc Crips
•W/S 113 Original Blocc Crips
•W/S 111 Neighborhood Crips
•W/S 115 Neighborhood Crips
As of 1993, UGBC's territory used these streets as borders:
•103th to The North
•108th to The South
•Normandie Avenue to The East
•Denker Avenue to The West
UGBC's territory was reffered and still is reffered to as "The Trenches" or "The Ends" due to its high violence rate, considering it's bordering 107 Hoover Gangster Crips, who they have a big rivality with. That rivality had brought Normandie Avenue the name of "D-Day" and UGBC's territory to be known amongst The 100s as "The Gates" due to their borderline war.
