15. The Mafia’s Growth in New York City

By the early twentieth century, Italian criminal gangs had formed in the Northeast. Most notably in New York City, as America became increasingly attractive to Italian immigrants. They were small scale operations, little different from other NYC gangs, generally operating in Italian neighborhoods and preying upon Italian immigrants. That changed in 1920, after passage of the 18th Amendment and the introduction of Prohibition, banning the manufacture, transport, or sale of alcohol. Making alcohol illegal did not reduce the high demand for alcohol, however, and simply created an environment of widespread tolerance of crime in order to provide a thirsty public with the booze it craved. Essentially, Prohibition took a major American industry, hitherto operated legally, and gifted it to organized crime.
