The Saint Valentine's Day Massacre is the name given to the 1929 murder of seven mob associates as part of a prohibition era conflict between two powerful criminal gangs in Chicago: the South Side Italian gang led by Al Capone and the North Side Irish gang led by Bugs Moran. Former members of the Egan's Rats gang were also suspected of having played a significant role in the incident, assisting Capone.
