Piscataqua River in the context of "Kittery, Maine"

The Province of New Hampshire was an English colony and later a British province in New England. It corresponds to the territory between the Merrimack and Piscataqua rivers on the eastern coast of North America. It was named after the English county of Hampshire in southern England by Captain John Mason in 1629, its first named proprietor. In 1776, the province established an independent state and government, the State of New Hampshire, and joined with twelve other colonies to form the United States.

Europeans first settled New Hampshire in the 1620s, and the province consisted for many years of a small number of communities along the seacoast, Piscataqua River, and Great Bay. In 1641 the communities were organized under the government of the Massachusetts Bay Colony, until Charles II issued a colonial charter for the province and appointed John Cutt as President of New Hampshire in 1679. After a brief period as a separate province, the territory was absorbed into the Dominion of New England in 1686. Following the collapse of the unpopular Dominion, on October 7, 1691 New Hampshire was again separated from Massachusetts and organized as an English crown colony. Its charter was enacted on May 14, 1692, during the coregency of William and Mary, the joint monarchs of England, Scotland, and Ireland. Between 1699 and 1741, the province's governor was often concurrently the governor of the Province of Massachusetts Bay. This practice ended completely in 1741, when Benning Wentworth was appointed governor. Wentworth laid claim on behalf of the province to lands west of the Connecticut River, east of the Hudson River, and north of Massachusetts, issuing controversial land grants that were disputed by the Province of New York, which also claimed the territory. These disputes resulted in the eventual formation of the Vermont Republic and the U.S. state of Vermont.

Piscataway (English pronunciation: /pɪsˈkætəweɪ/ ) is a township in Middlesex County, in the U.S. state of New Jersey. It is a suburb of the New York metropolitan area, in the Raritan Valley. As of the 2020 United States census, the township was the eighth most populous municipality of any kind in Central Jersey with a population of 60,804, an increase of 4,760 (+8.5%) from the 2010 census count of 56,044, which in turn reflected an increase of 5,562 (+11.0%) from 50,482 at the 2000 census.

The name may be derived from the area's earliest European settlers who came from near the Piscataqua River, a landmark defining the coastal border between New Hampshire and Maine, whose name derives from peske (branch) and tegwe (tidal river), or alternatively from pisgeu (meaning "dark night") and awa ("place of") or from a Lenape language word meaning "great deer". The area was appropriated in 1666 by Quakers and Baptists who had left the Puritan colony in New Hampshire.

Fort William and Mary was a colonial-era British fortress on the island of New Castle, at the mouth of the Piscataqua River in the Province of New Hampshire. Originally known as "The Castle," it was renamed Fort William and Mary circa 1692, after the accession of William III and Mary II to the British throne. During the American Revolutionary War (1775–1783) it was captured by rebel forces, recaptured, and later abandoned by the British. Following an 1808 rebuilding in response to increasing British hostilities, it was renamed Fort Constitution and served in the War of 1812. Another rebuilding and expansion was carried out in the wake of the Spanish-American War in 1899. The fort served actively through the first half of the 20th century and World War II.

Fort Constitution was given to the State of New Hampshire by the American military in 1961 and converted into a state park. Listed on the National Register of Historic Places in 1973, it is open to the public.

York County is both the southernmost and the westernmost county in the U.S. state of Maine, along the state of New Hampshire's eastern border. It is divided from Strafford County, New Hampshire, by the Salmon Falls River and the connected tidal estuary, the Piscataqua River. York County was permanently established in 1636. Several of Maine's earliest colonial settlements are found in the county, which is the state's oldest and one of the oldest in the United States. As of the 2020 census, its population was 211,972, making it Maine's second-most populous county. Its county seat is Alfred. York County is part of the Portland–South Portland, Maine Metropolitan Statistical Area.

Fort McClary is a former defensive fortification of the United States military located along the southern coast at Kittery Point, Maine at the mouth of the Piscataqua River. It was used throughout the 19th century to protect approaches to the harbor of Portsmouth, New Hampshire and the Portsmouth Naval Shipyard in Kittery. The property and its surviving structures are now owned and operated by the State of Maine as Fort McClary State Historic Site, including a blockhouse dating from 1844.

Great Bay is a tidal estuary located in Strafford and Rockingham counties in eastern New Hampshire, United States. The bay occupies over 6,000 acres (24 km), not including its several tidal river tributaries. Its outlet is at Hilton Point in Dover, New Hampshire, where waters from the bay flow into the Piscataqua River, thence proceeding southeast to the Atlantic Ocean near Portsmouth. The northern end of the bay, near its outlet, is referred to as Little Bay.

Portsmouth is a city in Rockingham County, New Hampshire, United States. At the 2020 census it had a population of 21,956. A historic seaport and popular summer tourist destination on the Piscataqua River bordering the state of Maine, Portsmouth was formerly the home of the Strategic Air Command's Pease Air Force Base, since converted to Portsmouth International Airport at Pease.

The Province of Maine refers to any of the various English colonies established in the 17th century along the northeast coast of North America, within portions of the present-day U.S. states of Maine, New Hampshire, and Vermont, and the Canadian provinces of Quebec and New Brunswick. It existed through a series of land patents made by the kings of England during this era, and included New Somersetshire, Lygonia, and Falmouth (now Portland, Maine). The province was incorporated into the Massachusetts Bay Colony during the 1650s, beginning with the formation of York County, Massachusetts, which extended from the Piscataqua River to just east of the mouth of the Presumpscot River in Casco Bay. Eventually, its territory grew to encompass nearly all of present-day Maine.
