Boston Massacre

The Boston Massacre, known in Great Britain as the Incident on King Street, was a confrontation on March 5, 1770, in the prelude to the American Revolution in Boston, in what was then the colony of the Province of Massachusetts Bay.

In the confrontation, nine British soldiers shot several in a crowd, estimated between 300 and 400, who were harassing them verbally and throwing various projectiles. Five American colonists were killed. The event was subsequently described as "a massacre" by Samuel Adams, Paul Revere, and other leading Patriots who later became central proponents of independence during the American Revolution and Revolutionary War. British troops had been stationed in the Province of Massachusetts Bay since 1768 in order to support Crown-appointed officials and to enforce unpopular legislation implemented by the British Parliament.

Amid tense relations between the civilians and the soldiers, a mob formed around a British sentry and verbally abused him. He was eventually supported by seven additional soldiers, led by Captain Thomas Preston, who were hit by clubs, stones, and snowballs. Eventually, one soldier fired, prompting the others to fire without an order by Preston. The gunfire instantly killed three people and wounded eight others, two of whom later died of their wounds.

The crowd eventually dispersed after acting governor Thomas Hutchinson promised an inquiry, but they reformed the next day, prompting the withdrawal of the troops to Castle Island.
