In the early 1900's, highly organised gangs emerged to rule the streets, as the gangster life became a quick road out of poverty.
When the manufacture, sale and distribution of alcohol was banned in 1920, a bootlegging industry flourished overnight. It was highly organized ; it was trans-national ; it generated millions of dollars. And it gave birth to the Mob.
How the Mob operated like an underworld business corporate is the most fascinating part of the Gangster story. It began in 1930s New York by Salvatore 'Charlie Lucky' Luciano.
