Answer:
The French Indian War/ Seven years war
Step-by-step explanation:
The French Indian War/ Seven years war lasted for seven Years, and nearly doubled Great Britain's national debt. In order to meet up with it the cost of war, the Crown sought sources of revenue to pay it off and attempted to impose new taxes on its colonies. These attempts were met with a strong resistance, until troops were called in to enforce the Crown's authority, which then led to the start of the American Revolutionary War. The French/Indian war was a war between the colonies of British America against those of New France, These two nations were on each side supported by military units from their country and by American Indian allies.
