The American Revolutionary War, often referred to as the uprising of 1776, sought independence from British rule. The conflict began in earnest in 1775 with growing discontent among the Thirteen Colonies due to British taxation without representation and other oppressive measures. The Declaration of Independence, adopted on July 4, 1776, formally announced the colonies' separation from Britain. This conflict ultimately escalated into a full-scale war lasting until 1783, leading to the establishment of the United States as a sovereign nation. The revolution significantly influenced global perspectives on governance, individual rights, and democratic ideals.
