Boston Massacre in the context of "Gaspee Affair"

The American Revolution (1765–1783) was a political conflict involving the Thirteen Colonies and Great Britain, culminating in the American Revolutionary War and the independence of the colonies as the United States. The Second Continental Congress established the Continental Army and appointed George Washington as its commander-in-chief in 1775. The following year, the Congress unanimously adopted the Declaration of Independence. Throughout most of the war, the outcome appeared uncertain. However, in 1781, a decisive victory by Washington and the Continental Army in the Siege of Yorktown led King George III and the British to negotiate the cessation of colonial rule and the acknowledgment of American independence, formalized in the Treaty of Paris in 1783.

Discontent with colonial rule began shortly after the French and Indian War in 1763. Even though the colonies had fought in and supported the war, the British Parliament imposed new taxes to compensate for wartime costs and transferred control of the colonies' western lands to British officials in Montreal. Representatives from several colonies convened the Stamp Act Congress in 1765; its "Declaration of Rights and Grievances" argued that taxation without representation violated their rights as Englishmen. In 1767, tensions flared again following British Parliament's passage of the Townshend Acts. In an effort to quell the mounting rebellion, King George III deployed British troops to Boston, where they killed protesters in the Boston Massacre in 1770. In December 1773, Sons of Liberty activists instigated the Boston Tea Party, during which they dumped chests of tea owned by the British East India Company into Boston Harbor. London responded by enacting a series of punitive laws, which effectively ended self-government in Massachusetts but also intensified the revolutionary cause.

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.

Boston is the capital and most populous city of the U.S. state of Massachusetts. It serves as the cultural and financial center of New England, a region of the Northeastern United States. Boston has an area of 48.4 sq mi (125 km) and a population of 675,647 as of the 2020 census, making it the third-most populous city in the Northeastern United States after New York City and Philadelphia. The larger Greater Boston metropolitan statistical area had a population of 4.9 million in 2023, making it the largest metropolitan area in New England and the eleventh-largest in the United States.

Boston was founded on Shawmut Peninsula in 1630 by English Puritan settlers, who named the city after the market town of Boston, Lincolnshire in England. During the American Revolution and Revolutionary War, Boston was home to several seminal events, including the Boston Massacre (1770), the Boston Tea Party (1773), Paul Revere's midnight ride (1775), the Battle of Bunker Hill (1775), and the Siege of Boston (1775–1776).

John Adams (October 30, 1735 – July 4, 1826) was a Founding Father and the second president of the United States from 1797 to 1801. Before his presidency, he was a leader of the American Revolution that achieved independence from Great Britain. During the latter part of the Revolutionary War and in the early years of the new nation, he served the Continental Congress of the United States as a senior diplomat in Europe. Adams was the first person to hold the office of vice president of the United States, serving from 1789 to 1797. He was a dedicated diarist and regularly corresponded with important contemporaries, including his wife and advisor Abigail Adams and his friend and rival Thomas Jefferson.

A lawyer and political activist prior to the Revolution, Adams was devoted to the right to counsel and presumption of innocence. He defied anti-British sentiment and successfully defended British soldiers against murder charges arising from the Boston Massacre. Adams was a Massachusetts delegate to the Continental Congress and became a leader of the revolution. He assisted Jefferson in drafting the Declaration of Independence in 1776 and was its primary advocate in Congress. As a diplomat, he represented the United States in France and the Netherlands during the war. He helped negotiate the peace treaty with Great Britain, secured Dutch loans for the American government, and was the first United States ambassador to Great Britain. Adams was the primary author of the Massachusetts Constitution in 1780, which, with his other political writings, influenced the United States Constitution.

The American Revolution (1765–1783) was a political conflict involving the Thirteen Colonies and Great Britain, that began as a rebellion demanding reform and evolved into a revolution that resulted in a complete separation that entirely replaced the social and political order, as an outcome of the American Revolutionary War and the resulting sovereign independence of the former colonies as the United States. The Second Continental Congress established the Continental Army and appointed George Washington as its commander-in-chief in 1775. The following year, the Congress unanimously adopted the Declaration of Independence. Throughout most of the war, the outcome appeared uncertain. However, in 1781, a decisive victory by Washington and the Continental Army in the Siege of Yorktown led King George III and the British to negotiate the cessation of colonial rule and the acknowledgment of American independence, formalized in the Treaty of Paris in 1783.

Discontent with colonial rule began shortly after the French and Indian War in 1763. Even though the colonies had fought in and supported the war directly with funds and materiel, the British Parliament imposed new taxes to ostensibly compensate for wartime costs and transferred control of the colonies' western lands to British officials in Montreal. Representatives from several colonies convened the Stamp Act Congress in 1765; its "Declaration of Rights and Grievances" argued in part that this taxation without representation violated their rights as Englishmen. In 1767, tensions flared again following British Parliament's passage of the Townshend Acts. In an effort to quell the mounting rebellion, King George III deployed British troops to Boston, where they killed antagonists in the Boston Massacre in 1770. In December 1773, the underground Sons of Liberty orchestrated the Boston Tea Party, during which they dumped chests of taxed tea owned by the British East India Company into Boston Harbor. Parliament responded by enacting a series of punitive laws, which effectively ended self-government in Massachusetts but also intensified support for the revolutionary cause.

Henry Knox (July 25, 1750 – October 25, 1806) was an American military officer, politician, bookseller, and a Founding Father of the United States. Knox, born in Boston, became a senior general of the Continental Army during the Revolutionary War, serving as chief of artillery in all of George Washington's campaigns. Following the war, he oversaw the War Department under the Articles of Confederation from 1785 to 1789. Washington appointed him the nation's first Secretary of War, a position which he held from 1789 to 1794. He is well known today as the namesake of Fort Knox in Kentucky, which is often conflated with the adjacent United States Bullion Depository.

Knox was born and raised in Boston where he owned and operated a bookstore, cultivating an interest in military history and joining a local artillery company. He was also on the scene of the 1770 Boston Massacre. He was barely 25 when the Revolutionary War broke out in 1775, but he engineered the transport of what became the "noble train of artillery", British ordnance captured from Fort Ticonderoga in New York, which proved decisive in the British evacuation of Boston in early 1776. Knox quickly rose to become the chief artillery officer of the Continental Army. In this role, he accompanied Washington on all of his campaigns and was engaged in the major actions of the war. He established training centers for artillerymen and manufacturing facilities for weaponry that were valuable assets in winning the war for independence.
