What was signed in 1783 to officially end the American Revolutionary War?

The Treaty of Paris, signed in 1783, officially ended the American Revolutionary War and recognized the thirteen colonies' independence from British rule. This treaty was a culmination of negotiations that had begun while the war was still ongoing and involved representatives from the United States and Great Britain.

The significance of the Treaty of Paris lies in its formal acknowledgment of the United States as a sovereign nation, which was crucial for the establishment of its own government and the development of its identity as an independent state. It not only marked the end of military conflict but also laid the foundation for future relations between the United States and other countries.

The other options represent important historical documents and events but do not pertain to the conclusion of the Revolutionary War. For instance, the Magna Carta, signed in 1215, was an early document limiting the powers of the English king, while the Articles of Confederation served as the first constitution of the United States post-war (ratified in 1781), governing the country until replaced by the current Constitution in 1789, which established a stronger federal government.
