Johnny Torrio Chicago's First Modern Gang Lord

Johnny Torrio is sometimes seen as a footnote to Al Capone who is most often associated with the heyday of Chicago criminal activity. Yet it was Torrio who moved from Italy to New York to Chicago who established the first empire in Chicago. At the time there were two rival gangs in the windy city, They dealt in gambling, prostitution, extortion, liquor running, etc. The O'Banion gang was a bitter rival of first Torrio and later Al Capone.
