The event traced back to the Boston Massacre in 1770 is the growing tension and conflict that ultimately led to the American Revolution. The Boston Massacre occurred when British soldiers fired into a crowd of colonists protesting British taxes and military presence, killing five individuals. This violent incident intensified anti-British sentiments and was utilized as propaganda by colonial leaders like Samuel Adams to galvanize public opposition to British rule. The event became a rallying point for the revolutionary cause, highlighting the colonists’ grievances and escalating calls for independence, contributing significantly to the eventual outbreak of the Revolutionary War in 1775.
