The United States fought the American Revolutionary War (1775-1783) to free itself from British rule. Tensions had been escalating between the American colonies and the British government over issues such as taxation without representation, trade restrictions, and lack of colonial autonomy. The war was marked by various battles and significant events, including the Declaration of Independence in 1776, which articulated the colonies' desire for freedom. The conflict ended with the Treaty of Paris in 1783, formally recognizing the independence of the United States and establishing its borders, thus paving the way for the development of a new nation.
