Irish mob

The Irish mob is a collection of organized crime groups composed of largely ethnic Irish members which operate primarily in the United States and have existed since the early 19th century. Originating in Irish-American street gangs – famously first depicted in Herbert Asbury's 1927 book, The Gangs of New York – the Irish Mob has appeared in most major American and Canadian cities, especially in the Northeast and the urban industrial Midwest, including Boston, New York City, Philadelphia, Pittsburgh, Baltimore, Cleveland, and Chicago.
