Why would “No Taxation without Representation” propel the colonist to go to war?

The American Revolution was the time the thirteen colonies fought for their independence from Britain. The revolution occurred from the aftermath of numerous events, including the Boston Massacre. The Boston Massacre was thought out as a propaganda event for colonialist, to aid for more support in the cause for the American Revolution. The tenacity for Britain to keep ahold their colonists loosened and like a rubber band, tensions within the two groups snapped. British soldiers were sent to Boston and fired upon the Boston mob, leaving five men dead after the end of the chaos. Trials took place to defend the soldiers in order to defend their rights as individuals. A fast occurrence, though, placed a scar onto the colonists to propel them to fight against Britain.
