The
Saint Valentine's Day Massacre is the name given to the 1929 murder of seven mob associates and a mechanic of the
North Side Irish gang led by
Bugs Moran during the
Prohibition Era. It resulted from the struggle between the Irish American gang and the
South Side Italian gang led by
Al Capone to take control of organized crime in Chicago. Former members of the
Egan's Rats gang were also suspected of having played a significant role in the incident, assisting Capone.
