The major historical event that began in 1775 and ended in 1783 in North America is the American Revolutionary War. This conflict was fought between the thirteen American colonies and Great Britain, stemming from colonial discontent over British taxation and governance without representation. The war was marked by significant battles such as Lexington and Concord, Bunker Hill, and Yorktown. With the support of France and other allies, the colonies achieved victory, leading to the Treaty of Paris in 1783, which recognized their independence. The war fundamentally transformed political ideologies and laid the foundation for the United States as an independent nation.
