The Boston Massacre was an incident on March 5, 1770, in which British Army soldiers killed five male civilians and injured six others. British troops had been stationed in Boston, capital of the Province of Massachusetts Bay, since 1768 in order to protect and support crown-appointed colonial officials attempting to enforce unpopular Parliamentary legislation. Amid ongoing tense relations between the population and the soldiers, a mob formed around a British sentry, who was subjected to verbal abuse and harassment. He was eventually supported by eight additional soldiers, who were subjected to verbal threats and thrown objects. They fired into the crowd, without orders. Depictions, reports, and propaganda about the event, notably the colored engraving produced by Paul Revere further heightened tensions throughout the Thirteen Colonies.
