Lee Resolution in the context of "United States Declaration of Independence"

The American Revolutionary War (April 19, 1775 – September 3, 1783), also known as the Revolutionary War or American War of Independence, was the armed conflict that comprised the final eight years of the broader American Revolution, in which American Patriot forces organized as the Continental Army and commanded by George Washington defeated the British Army. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war's outcome seemed uncertain for most of the war, but Washington and the Continental Army's decisive victory in the Siege of Yorktown in 1781 led King George III and the Kingdom of Great Britain to negotiate an end to the war. In 1783, in the Treaty of Paris, the British monarchy acknowledged the independence of the Thirteen Colonies, leading to the establishment of the United States as an independent and sovereign nation.

In 1763, after the British Empire gained dominance in North America following its victory over the French in the Seven Years' War, tensions and disputes began escalating between the British and the Thirteen Colonies, especially following passage of Stamp and Townshend Acts. The British Army responded by seeking to occupy Boston militarily, leading to the Boston Massacre on March 5, 1770. In mid-1774, with tensions escalating even further between the British Army and the colonies, the British Parliament imposed the Intolerable Acts, an attempt to disarm Americans, leading to the Battles of Lexington and Concord in April 1775, the first battles of the Revolutionary War. In June 1775, the Second Continental Congress voted to incorporate colonial-based Patriot militias into a central military, the Continental Army, and unanimously appointed Washington its commander-in-chief. Two months later, in August 1775, the British Parliament declared the colonies to be in a state of rebellion. In July 1776, the Second Continental Congress formalized the war, passing the Lee Resolution on July 2, and, two days later, unanimously adopting the Declaration of Independence, on July 4.

The United States of America was formed after thirteen British colonies in North America declared independence from the British Empire on July 4, 1776. In the Lee Resolution, passed by the Second Continental Congress two days prior, the colonies resolved that they were free and independent states. The union was formalized in the Articles of Confederation, which came into force on March 1, 1781, after being ratified by all 13 states. Their independence was recognized by Great Britain in the Treaty of Paris of 1783, which concluded the American Revolutionary War. This effectively doubled the size of the colonies, now able to stretch west past the Proclamation Line to the Mississippi River. This land was organized into territories and then states, though there remained some conflict with the sea-to-sea grants claimed by some of the original colonies. In time, these grants were ceded to the federal government.

The first great expansion of the country came with the Louisiana Purchase of 1803, which doubled the country's territory, although the southeastern border with Spanish Florida was the subject of much dispute until it and Spanish claims to the Oregon Country were ceded to the US in 1821. The Oregon Country gave the United States access to the Pacific Ocean, though it was shared for a time with the United Kingdom. The annexation of the Republic of Texas in 1845 led directly to the Mexican–American War, after which the victorious United States obtained the northern half of Mexico's territory, including what was quickly made the state of California.

The Second Continental Congress (1775–1781) was the meeting of delegates from the Thirteen Colonies that united in support of the American Revolution and Revolutionary War, which established American independence from the British Empire. The Congress constituted a new federation that it first named the United Colonies of North America, and in 1776, renamed the United States of America. The Congress began convening in present-day Independence Hall in Philadelphia, on May 10, 1775, with representatives from 12 of the 13 colonies, following the Battles of Lexington and Concord, the first battles of the Revolutionary War, which were fought on April 19, 1775.

The Second Continental Congress succeeded the First Continental Congress, which met from September 5 to October 26, 1774, also in Philadelphia. The Second Congress functioned as the de facto federation government at the outset of the Revolutionary War by raising militias, directing strategy, appointing diplomats, and writing petitions such as the Declaration of the Causes and Necessity of Taking Up Arms and the Olive Branch Petition. All 13 colonies were represented by the time the Congress adopted the Lee Resolution, which declared independence from Great Britain on July 2, 1776, and the Congress unanimously agreed to the Declaration of Independence two days later.

The Continental Congress was a series of legislative bodies, with some executive function, who acted as the Provisional Government for the Thirteen Colonies of Great Britain in North America, and the newly declared United States before, during, and after the American Revolutionary War. The Continental Congress refers to both the First and Second Congresses of 1774–1781 and at the time, also described the Congress of the Confederation of 1781–1789. The Confederation Congress operated as the first federal government until being replaced following ratification of the U.S. Constitution. Until 1785, the Congress met predominantly at what is today Independence Hall in Philadelphia, though it was relocated temporarily on several occasions during the Revolutionary War and the fall of Philadelphia.

The First Continental Congress convened in Philadelphia in 1774 in response to escalating tensions between the colonies and the British, which culminated in passage of the Intolerable Acts by the British Parliament following the Boston Tea Party. The First Congress met for about six weeks, mainly to try to repair the fraying relationship between Britain and the colonies while asserting the rights of colonists, proclaiming and passing the Continental Association, which was a unified trade embargo against Britain, and successfully building consensus for establishment of a second congress. The Second Continental Congress convened in 1775, soon after hostilities broke out in Massachusetts. Soon after meeting, the Second Congress sent the Olive Branch Petition to King George III, established the Continental Army, and elected George Washington commander of the new army. After the king issued the Proclamation of Rebellion in August 1775 in response to the Battle of Bunker Hill, some members of the Second Congress concluded that peace with Britain would not be forthcoming, and began working towards unifying the colonies into a new nation. The body adopted the Lee Resolution for Independence on July 2, 1776, and the Declaration of Independence two days later, on July 4, 1776, proclaiming that the former colonies were now independent sovereign states.
