The rebellion led by a group of colonial settlers against British rule in 1775 is known as the American Revolution. Tensions had been brewing due to British taxation without representation, leading to increasing discontent among the colonies. The revolution began with skirmishes at Lexington and Concord, and ultimately, it sought independence from British rule. The conflict lasted until 1783, culminating in the establishment of the United States as an independent nation, marking a significant moment in the history of democracy and self-governance.
