Cause: Bostonians did not like the presence of British troops and thought of them as foreign enemies. The soliders knew that they were not welcomed. Both sides resented each other, and name-calling, arguments, and fights between Bostonians and the soliders were common. On March 5, 1770, a British soldier had an argument with a colonist and struck him. A crowd gathered around the soldier, throwing snowballs and shouting insults. Soon a small number of troops arrived. The crowd grew louder and angrier by the moment.
Effect: The soliders fired into the crowd, killing five men.
