Nicola Sacco and Bartolomeo Vanzetti were anarchists who were convicted of murdering two men during a 1920 armed robbery in South Braintree, Massachusetts. After a controversial trial and a series of appeals, the two Italian immigrants were executed on August 23, 1927.
There is a highly politicized dispute over their guilt or innocence, as well as whether or not the trials were fair. Very little evidence linked them to this crime. The dispute focuses on small details and contradictory evidence. As a result, historians have not reached a consensus.
