Mafia
The mafia in New York began when thousands of Italians moved there in the late 19th century and the early 20th century to find a better life. Many Irish and Germans also moved there for the same reasons. Many of those people set up a business or worked for businesses that were already there. Most earned very little money, and some of them, who were tired of being poor, decided to earn money from crime so that they could make more than by working.
