 The Boston Massacre is considered one of the most significant events that turned colonial sentiment against King George III and British Parliamentary authority.John Adams wrote that the "foundation of American independence was laid" on March 5, 1770, and Samuel Adams and other Patriots used annual commemorations (Massacre Day) to encourage public sentiment toward independence.Christopher Monk was the boy who was wounded in the attack and died in 1780, and his memory was honored as a reminder of British hostility.
