National Crime Syndicate
The National Crime Syndicate was the name given by the press to the multi-ethnic, loosely connected American confederation of several criminal organizations. It mostly consisted of and was led by the closely interconnected Italian-American Mafia and Jewish mob; to a lesser extent, it also involved other criminal organizations such as the Irish Mob and African-American organized crime groups. Hundreds of murders were committed by Murder, Inc. on behalf of the National Crime Syndicate during the 1930s and 1940s.
