I think this link is a good representation of how conflict theory evolves.

The mafia is the accurate symbol of the conflict theory. There have been countless movies and television shows depicting the mafia. They are seen as bullies, who use scare tactics and intimidation to get what they want. These tactics often include beatings and even murder. They make people fall in line and do what they want because they are fearful of the repercussions if they don't.
Although the exact origins of the mafia are a little sketchy, it is thought that its early days began in the 1860's in Sicily, Italy. Italy annexed Sicily, redistributed the land to private citizens and removed their armies from the island. With more property owners, there were more disputes that needed settling, contracts to enforce and properties to protect. There were only about 350 law enforcement officers for the entire island. Some cities were only visited by police every few months. Property owners turned to people outside the law to arbitrate disputes and protection. These people eventually organized themselves into the first Mafia clan. They use threats of violence to protect their clients from fraud, thieves, and competitors.
This is a very interesting YouTube video on the mafia and its code of conduct.

This site has a vast amount of information on different aspects of conflict theory.

The FBI site gives a lot of background information on the mafia, different families and links to other related topics. I found it very helpful.

“Men make their own history, but they do not make it just as they please; they do not make it under circumstances chosen by themselves, but under circumstances directly encountered, given and transmitted from the past. The tradition of all the dead generations weighs like a nightmare on the brain of the living.”
― Karl Marx
