The French and Indian War changed this relationship by making
it a great deal worse. In fact, the war can be said to have led to the
revolution.
First, the war took the French out of North America. The colonists
no longer had to fear being taken by France if they were to break free
from Britain.
Second and more importantly, the war cost a huge amount of money. The
British felt that the colonies should pay some part of that sum. The
colonists had not been taxed as heavily as the people in Britain itself
and the British government felt this should change. The taxes that the
British then imposed on the colonies were the major cause of the
discontent that led to the Revolutionary War.
