King George III was the king during the American Revolution in England. His policies and taxation measures instigated widespread discontent among the American colonies, leading to heightened tensions and ultimately rebellion. From imposing taxes without representation to enforcing the Quartering Act, George III's rule is often viewed as a symbol of tyrannical governance. The colonists' dissatisfaction culminated in the Declaration of Independence in 1776 and the ensuing Revolutionary War, which sought to achieve autonomy from British control. His reign and the resulting revolution significantly influenced the course of American history and the establishment of a democratic government.
