Great Britain justified raising taxes on colonists because of which event? British merchants being denied entry into colony ports colonists picking up arms against British soldiers and merchants American Indians receiving more trading from colonists British debt from defending the colonies in the French and Indian War



Their democratically elected Parliament passing laws to that effect. 

The purpose of the taxes was to raise about 1/3 of the cost of permanently stationing British troops in the American colonies to guard against outside attacks - there was no specific "event" that led to this.
