Boston Harbor in the context of "Charlestown, Boston"

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 First Continental Congress was a meeting of delegates of twelve of the Thirteen Colonies (Georgia did not attend) held from September 5 to October 26, 1774, at Carpenters' Hall in Philadelphia at the beginning of the American Revolution. The meeting was organized by the delegates after the British Navy implemented a blockade of Boston Harbor and the Parliament of Great Britain passed the punitive Intolerable Acts in response to the Boston Tea Party.

During the opening weeks of the Congress, the delegates conducted a spirited discussion about how the colonies could collectively respond to the British government's coercive actions, and they worked to make a common cause. As a prelude to its decisions, the Congress's first action was the adoption of the Suffolk Resolves, a measure drawn up by several counties in Massachusetts that included a declaration of grievances, called for a trade boycott of British goods, and urged each colony to set up and train its own militia. A less radical plan was then proposed to create a Union of Great Britain and the Colonies, but the delegates tabled the measure and later struck it from the record of their proceedings.

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.

The Custom House in Boston, Massachusetts, was established in the 17th century and stood near the waterfront in several successive locations through the years. In 1849 the U.S. federal government constructed a neoclassical building on State Street; it remains the "Custom House" known to Bostonians today. A tower was added in 1915; the building joined the National Register of Historic Places in 1973 and was designated a Boston Landmark by the Boston Landmarks Commission in 1986.

The Port of Boston (AMS Seaport Code: 0401, UN/LOCODE: US BOS) is a major seaport located in Boston Harbor and adjacent to the City of Boston. It is the largest port in Massachusetts and one of the principal ports on the East Coast of the United States.

The Port of Boston was historically important for the growth of the City of Boston, and was originally located in what is now the downtown area of the city, called Long Wharf. Land reclamation and conversion to other uses means that the downtown area no longer handles commercial traffic, although there is still considerable ferry and leisure usage at Long Wharf. Today the principal cargo handling facilities are located in the Boston neighborhoods of Charlestown, East Boston, and South Boston, and in the neighboring city of Everett. The Port of Boston has also been an entry point for many immigrants.

Boston's diverse neighborhoods serve as a political and cultural organizing mechanism. The City of Boston's Office of Neighborhood Services has designated 23 Neighborhoods in the city:

The islands in Boston Harbor are administered as part of the Boston Harbor Islands National Recreation Area.

Hingham (/ˈhɪŋəm/ HING-əm) is a town in northern Plymouth County in the U.S. state of Massachusetts. Part of the Greater Boston region, it is located on the South Shore of Massachusetts. At the 2020 census, the population was 24,284. It contains the census-designated place of the same name. Hingham is known for its colonial history and location on Boston Harbor. The town was named after Hingham, Norfolk, England, and was first settled by English colonists in 1633.

Charlestown is the oldest neighborhood in Boston, Massachusetts, in the United States. Also called Mishawum by the Massachusett, it is located on a peninsula north of the Charles River, across from downtown Boston, and also adjoins the Mystic River and Boston Harbor waterways. Charlestown was laid out in 1629 by engineer Thomas Graves, one of its earliest settlers, during the reign of Charles I of England. It was originally a separate town and the first capital of the Massachusetts Bay Colony.

Charlestown became a city in 1848 and was annexed by Boston on January 5, 1874. With that, it also switched from Middlesex County, to which it had belonged since 1643, to Suffolk County. It has had a substantial Irish-American population since the migration of Irish people during the Great Irish Famine of the 1840s. Since the late 1980s, the neighborhood has changed dramatically because of its proximity to downtown and its colonial architecture. A mix of yuppie and upper-middle-class gentrification has influenced much of the area, as it has in many of Boston's neighborhoods, but Charlestown still maintains a strong Irish-American population.
