There were gangs in the ancient world.
Of course
A better question would be: Is there a state that doesn't have gangs? Probably not, I would imagine every state has them. They are literally in all 50 states including Alaska. There are Indian gangs, Black, White and Latino Gangs. Asian Gangs have been around for a long time.
This is impossible to do since at last report there were over 60 active gangs in/around Fresno and Fresno County. One of the most active is the Bull Dog.
Gangs have been around for thousands of years.
I am a local in the city of Stockton and also a former gang member since the early 90's. I can name most of the gangs that were active and non-active. If I have to make an estimate I would have to say there are approximately over 30 gangs in Stockton. 2000- 2012 STOCKTON
There are gangs throughout the entire Triangle, and some are active in Holly Springs, although gang activity isn't a major problem in Holly Springs.

As far back as when Britain has been a country.
The Nuestra Familia started cause in prison gangs under the Mexican Mafia(more specifially the Surenos) would harass all the small Hispanic gangs who weren't under the Mexican Mafia. So other Hispanic gangs alligned & created the Nuestra Familia which the Nortenos used to be under. Nuestra Familia disbanded not too long after and some gangs that were under them later joined the Blood Alliance(or are no longer active).*Nortenos used to be under the Nuestra Familia but later joined the Bloods Alliance in the late 70's & have been that way ever since.
The New York mob has been around for a very long time, and still is. Its' most active time was from the 1920s' to the 1970s'. It is very inactive today compared to the days of old, and the stability of a mafia in the world of crime is impossible to sustain in America, so only gangs remain.
