The First Continental Congress met briefly in Carpenter's Hall in Philadelphia, Pennsylvania from September 5 to October 26, 1774. It consisted of fifty-six delegates from twelve of the Thirteen Colonies that would become the United States of America. The delegates, who included George Washington (then a colonel of the Virginia volunteers), Patrick Henry and John Adams were elected by their respective colonial assemblies. Other notable delegates included Samuel Adams from Massachusetts Bay, and Joseph Galloway and John Dickinson from Pennsylvania.[1] Peyton Randolph of Virginia was its president. Benjamin Franklin had put forth the idea of such a meeting the year before but was unable to convince the colonies of its necessity until the British placed a blockade at the Port of Boston in response to the Boston Tea Party in 1773. All of the colonies sent their delegates except Georgia, which needed the protection of British soldiers to contend with attacks from various Native American tribes. Most of the delegates were not yet ready to break away from Great Britain, but they wanted the British King and Parliament to act in what they considered a more fair manner. Convened in response to the Intolerable Acts passed by the British Parliament in 1774, the delegates organized an economic boycott of Great Britain in protest and petitioned the King for a redress of grievances. The colonies were united in their effort to demonstrate their authority to Great Britain by virtue of their common causes and through their unity, but their ultimate objectives were not consistent. Pennsylvania and New York had sent delegates with firm instructions to pursue a resolution with Great Britain. While the other colonies all held the idea of colonial rights as paramount, they were split between those who sought legislative equality with Britain and those who instead favored independence and a break from the Crown and its excesses. On October 26, 1774 the First Continental Congress adjourned but agreed to reconvene in May 1775 if Parliament still did not address their grievances. In London, Parliament debated the merits of meeting the demands made by the colonies; however, it took no official notice of Congress's petitions and addresses. On November 30, 1774, King George III opened Parliament with a speech condemning Massachusetts and the Suffolk Resolves. At that point it became clear that the Continental Congress would have to convene once again. The Second Continental Congress convened on May 10, 1775 at Philadelphia's State House, unanimously passing the Declaration of Independence on July 4, 1776. Thomas Jefferson of Virginia drafted the declaration and John Adams was a leader in the debates in favor of its adoption. John Hancock of Massachusetts was the president during those debates. To govern during the American Revolution, the Second Continental Congress continued, meeting at various locations, until it became Congress of the Confederation when the Articles of Confederation were ratified on March 1, 1781. The delegates, who included George Washington (then a colonel of the Virginia volunteers), Patrick Henry and John Adams were elected by their respective colonial assemblies. Other notable delegates included Samuel Adams from Massachusetts Bay, and Joseph Galloway and John Dickinson from Pennsylvania.

Event

The Treaty of Paris, signed in Paris by representatives of King George III of Great Britain and representatives of the United States of America on 3 September 1783, ended the American Revolutionary War. This treaty, along with the separate peace treaties between Great Britain and the nations that supported the American cause: France, Spain and the Dutch Republic, are known collectively as the Peace of Paris. Its territorial provisions were "exceedingly generous" to the United States in terms of enlarged boundaries. Peace negotiations began in April of 1782 , and continued through the summer. Representing the United States were Benjamin Franklin, John Jay, Henry Laurens, and John Adams.David Hartley and Richard Oswald represented Great Britain. The treaty was signed at the Hotel d'York (presently 56 Rue Jacob) in Paris on September 3, 1783 by Adams, Franklin, Jay, and Hartley. On the same day, Great Britain also signed separate agreements with France and Spain, and (provisionally) with the Netherlands. In the treaty with Spain, the territories of East and West Florida were ceded to Spain (without a clear northern boundary, resulting in a territorial dispute resolved by the Treaty of Madrid in 1795), as was the island of Minorca, while the Bahama Islands, Grenada, and Montserrat, captured by the French and Spanish, were returned to Britain. The treaty with France was mostly about exchanges of captured territory (France's only net gains were the island of Tobago, and Senegal in Africa), but also reinforced earlier treaties, guaranteeing fishing rights off Newfoundland. Dutch possessions in the East Indies, captured in 1781, were returned by Britain to the Netherlands in exchange for trading privileges in the Dutch East Indies, by a treaty which was not finalized until 1784. The United States Congress of the Confederation ratified the Treaty of Paris on January 14, 1784. Copies were sent back to Europe for ratification by the other parties involved, the first reaching France in March 1784. British ratification occurred on April 9, 1784, and the ratified versions were exchanged in Paris on May 12, 1784. It was not for some time, though, that the Americans in the countryside received the news because of the lack of speedy communication.
