The king of England during the American Revolution was King George III. He reigned from 1760 to 1820 and was a central figure in the conflict between Britain and its American colonies. His policies and the enforcement of British control over colonial governance, through measures such as taxation without representation and the Intolerable Acts, fueled discontent and ultimately led to calls for independence among the colonists. King George III’s determination to maintain Britain’s authority over the colonies contributed to the revolutionary tension, and he was viewed by American revolutionaries as a symbol of tyranny. His reign ended shortly after the conclusion of the war.
