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