This intensification of gang criminality was fueled by an accumulation of major and minor social, economic, and political factors. During this period the streets became more violent, and the gangs became more numerous and predatory. Within a few years of the first Crip gangs, Blood-suffixed gangs, although fewer in number, began to emerge with the same apparent irregular pattern as the Crips. By the early 1970s, new groups using Crip suffixes began to appear all over South Los Angeles. There were at least three factors associated with gang formation in this era: conflict, racism, and living in the projects.

The Watts gangs were at the peak of their power throughout most of the 1950s. Larger, more powerful, and more conflict-oriented gangs began to emerge in Watts, particularly in the government housing projects. After World War II and long before the arrival of the Bloods and Crips, the expansion of the black population was accompanied by a significant expansion of gangs. 14 B-Brazy, Peanut II and Lil' Laniak II were from the Denver Lanes. The two gangs have been close allies for decades and are still allied today. Denver Lane Bloods and the Crenshaw Mafia Bloods. Although many of these gangs, like the Boozies, had all black memberships, others, although primarily black, had other racial and ethnic members who reflected the racial and ethnic heterogeneity of the area. The core members of the Damu Ridas were from two different Blood gangs: the L.A. Other Los Angeles gangs emerged in this era as well. Stealing cars and scuffling with one another or others were apparently their primary offenses. The gang consisted of a relatively small group (not over 25) of 18- and 19-year-old black males.

A large family named Boozie, which lived in South Los Angeles, was the core of the Boozie gang, and the gang was involved in street crimes in the area.
