Can you tell me some details of the history of the mob in the United States?

The early origins of the American Mob can be traced back to the immigration of thousands of Irish and Italian peope to the United States during the 19th and early 20th centuries. These two groups found employment and refuge in cities such as New York, Philadelphia, Boston, and Chicago and quickly established strong gang networks. Prohibition in the 1920s and ‘30s greatly increased the influence and power of the mob, but their reign as the leading crime syndicates in the U.S. ended with the passage of the Racketeer Influenced and Corrupt Organizations (RICO) Act in 1970. Although the power and influence of the American Mob has diminished significantly since then, reminders of their influence remain visible in popular culture and some organized crime still exists in the US today.
