New Hampshire () is a state in the New England region of the northeastern United States. It is bordered by Massachusetts to the south, Vermont to the west, Maine and the Atlantic Ocean to the east, and the Canadian province of Quebec to the north. New Hampshire is the 5th smallest by area and the 10th least populous U.S. state. Concord is the state capital, while Manchester is the largest city. New Hampshire has no general sales tax, nor income tax other than on interest and dividends. The New Hampshire primary is the first primary in the U.S. presidential election cycle. Its license plates carry the state motto, “Live Free or Die”. The state’s nickname, “The Granite State”, refers to its extensive granite formations and quarries.

In January 1776, it became the first of the British North American colonies to establish a government independent of the Kingdom of Great Britain’s authority; it was the first to establish its own state constitution. Six months later, it became one of the original 13 colonies that signed the United States Declaration of Independence, and in June 1788 it was the ninth state to ratify the United States Constitution, bringing that document into effect. Historically, New Hampshire was a major center for textile manufacturing, shoemaking, and papermaking, with Amoskeag Manufacturing Company in Manchester at one time being the largest cotton textile plant in the world. Numerous mills were located along various rivers in the state, especially the Merrimack and Connecticut rivers. Many French Canadians migrated to New Hampshire to work the mills in the late 19th and early 20th century; New Hampshire still ranks second among states by percentage of people claiming French American ancestry, with 24.5% of the state identifying as such.

Manufacturing centers such as Manchester, Nashua and Berlin were hit hard in the 1930s–1940s as major manufacturing industries left New England and moved to the Southern United States or overseas, reflecting nationwide trends. In the 1950s and 1960s, defense contractors moved into many of the former mills, such as Sanders Associates in Nashua; the population of southern New Hampshire surged beginning in the 1980s as major highways connected the region to Greater Boston and established several bedroom communities in the state. With some of the highest ski mountains on the East Coast, New Hampshire’s major recreational attractions include skiing, snowmobiling, and other winter sports, hiking and mountaineering (Mount Monadnock in the state’s southwestern corner is among the most climbed mountains in the U.S.), observing the fall foliage, summer cottages along many lakes and the seacoast, motor sports at the New Hampshire Motor Speedway, and Motorcycle Week, a popular motorcycle rally held in Weirs Beach in Laconia in June. The White Mountain National Forest links the Vermont and Maine portions of the Appalachian Trail, and has the Mount Washington Auto Road, where visitors may drive to the top of 6,288-foot (1,917 m) Mount Washington.
