The king during the American Revolution was King George III of Great Britain. His reign saw the rise of colonial discontent due to various policies and taxes, such as the Stamp Act and the Tea Act, which fueled revolutionary sentiments among the American colonists. King George III's perceived tyranny and refusal to recognize the colonies' grievances ultimately led to the Revolutionary War. The conflict resulted in the American colonies gaining independence, drastically altering the political landscape and diminishing British power over its colonies, while also inspiring other independence movements worldwide.
