The seven years war fundamentally changed the relationship between Britain and its American colonies as the British thought that the American militia was poorly trained and disorderly. They also thought the colonists were useless because they were unwilling to help the troops. Moreover, the colonists hoped to reap the benefits in the form of access to the West lands and the British prohibited the colonies from settling in west. The war left Britain in debt and this debt caused Britain to tax colonies.These taxes irritated the colonies and rebel started against Britain.
