The area of New Hampshire was part of the original territory of the United States. It was originally included in the Charter of New England in 1620, but a separate grant established New Hampshire in 1629. In 1641, the area reunited with Massachusetts, and separated and reunited several times until it finally became a separate provincial government in 1741.
New Hampshire ratified the U.S. Constitution on June 21, 1788; it was the ninth of the original 13 states to join the Union. The state’s boundary with Canada was not formally established until the Webster-Ashburton Treaty of 1842, when New Hampshire assumed generally the same boundary as the present state.
Census data for New Hampshire are available beginning with the 1790 census.

Other Information Of General Geographic Interest
In New Hampshire, the entities with local government power are towns and cities. A town can become a city by obtaining a charter from the state legislature. Each charter provides for the form of government of each city. Towns and cities differ mainly because cities do not have a “town-meeting” form of government, but there are some towns that do not have meetings and are not “cities.” Changes to town boundaries are rare, but can occur if all towns affected by the changes agree with the decision.
