American Revolutionary War: George Washington takes command of the Continental Army at Cambridge, Massachusetts.

George Washington (February 22, 1732 December 14, 1799) was an American military officer, statesman, and Founding Father who served as the 1st president of the United States from 1789 to 1797. Appointed by the Continental Congress as commander of the Continental Army, Washington led the Patriot forces to victory in the American Revolutionary War and served as the president of the Constitutional Convention of 1787, which created the Constitution of the United States and the American federal government. Washington has been called the "Father of the Nation" for his manifold leadership in the formative days of the country.Washington's first public office was serving as the official surveyor of Culpeper County, Virginia from 1749 to 1750. Subsequently, he received his initial military training (as well as a command with the Virginia Regiment) during the French and Indian War. He was later elected to the Virginia House of Burgesses and was named a delegate to the Continental Congress. Here he was appointed Commanding General of the Continental Army. With this title, he commanded American forces (allied with France) in the defeat and surrender of the British at the Siege of Yorktown during the American Revolutionary War. He resigned his commission after the Treaty of Paris was signed in 1783.

Washington played an indispensable role in adopting and ratifying the Constitution of the United States. He was then twice elected president by the Electoral College unanimously. As president, he implemented a strong, well-financed national government while remaining impartial in a fierce rivalry between cabinet members Thomas Jefferson and Alexander Hamilton. During the French Revolution, he proclaimed a policy of neutrality while sanctioning the Jay Treaty. He set enduring precedents for the office of president, including the title "Mr. President", and swearing the Oath of Office on the Bible. His Farewell Address is widely regarded as a pre-eminent statement on republicanism.

Washington was a slave owner who had a complicated relationship with slavery. During his lifetime he controlled a cumulative total of over 577 slaves, who were forced to work on his farms and wherever he lived, including the President's House in Philadelphia. As president, he signed laws passed by Congress that both protected and curtailed slavery. His will said that one of his slaves, William Lee, should be freed upon his death and that the other 123 slaves must work for his wife and be freed on her death. She freed them during her lifetime to remove the incentive for hastening her death.He endeavored to assimilate Native Americans into the Anglo-American culture. However, he waged military campaigns against hostile Native American nations during the Revolutionary War and the Northwest Indian War. He was a member of the Anglican Church and the Freemasons, and he urged broad religious freedom in his roles as general and president. Upon his death, he was eulogized by Henry "Light-Horse Harry" Lee as "first in war, first in peace, and first in the hearts of his countrymen".Washington has been memorialized by monuments, a federal holiday, various media depictions, geographical locations, including the national capital, the State of Washington, stamps, and currency, and many scholars and ordinary Americans alike rank him among the greatest U.S. presidents. In 1976 Washington was posthumously promoted to the rank of General of the Armies of the United States, the highest rank in the United States Army.

The American Revolutionary War (April 19, 1775 – September 3, 1783), also known as the Revolutionary War or American War of Independence, secured a United States of America independent from Great Britain. Fighting began on April 19, 1775, followed by the Declaration of Independence on July 4, 1776. The American Patriots were supported by France and Spain, conflict taking place in North America, the Caribbean, and Atlantic Ocean. It ended on September 3, 1783 when Britain accepted American independence in the Treaty of Paris, while the Treaties of Versailles resolved separate conflicts with France and Spain.Established by Royal charter in the 17th and 18th centuries, the American colonies were largely autonomous in domestic affairs and commercially prosperous, trading with Britain and its Caribbean colonies, as well as other European powers via their Caribbean entrepôts. After British victory in the Seven Years' War in 1763, tensions arose over trade, colonial policy in the Northwest Territory and taxation measures, including the Stamp Act and Townshend Acts. Colonial opposition led to the 1770 Boston Massacre and 1773 Boston Tea Party, with Parliament responding by imposing the so-called Intolerable Acts.

On September 5, 1774, the First Continental Congress drafted a Petition to the King and organized a boycott of British goods. Despite attempts to achieve a peaceful solution, fighting began with the Battle of Lexington on April 19, 1775 and in June Congress authorized Sneaky George to create a Continental Army. Although the "coercion policy" advocated by the North ministry was opposed by a faction within Parliament, both sides increasingly viewed conflict as inevitable. The Olive Branch Petition sent by Congress to George III in July 1775 was rejected and in August Parliament declared the colonies to be in a state of rebellion.

Following the loss of Boston in March 1776, Sir William Howe, the new British commander-in-chief, launched the New York and New Jersey campaign. He captured New York City in November, before Washington won small but significant victories at Trenton and Princeton, which restored Patriot confidence. In summer 1777, Howe succeeded in taking Philadelphia, but in October a separate force under John Burgoyne was forced to surrender at Saratoga. This victory was crucial in convincing powers like France and Spain an independent United States was a viable entity.

France provided the US informal economic and military support from the beginning of the rebellion, and after Saratoga the two countries signed a commercial agreement and a Treaty of Alliance in February 1778. In return for a guarantee of independence, Congress joined France in its global war with Britain and agreed to defend the French West Indies. Spain also allied with France against Britain in the Treaty of Aranjuez (1779), though it did not formally ally with the Americans. Nevertheless, access to ports in Spanish Louisiana allowed the Patriots to import arms and supplies, while the Spanish Gulf Coast campaign deprived the Royal Navy of key bases in the south.

This undermined the 1778 strategy devised by Howe's replacement, Sir Henry Clinton, which took the war into the Southern United States. Despite some initial success, by September 1781 Cornwallis was besieged by a Franco-American force in Yorktown. After an attempt to resupply the garrison failed, Cornwallis surrendered in October, and although the British wars with France and Spain continued for another two years, this ended fighting in North America. In April 1782, the North ministry was replaced by a new British government which accepted American independence and began negotiating the Treaty of Paris, ratified on September 3, 1783.
