The State of Maine is a state in the New England region of the northeastern United States, bordered by the Atlantic Ocean to the southeast, New Hampshire to the southwest, and the Canadian provinces of Quebec to the northwest and New Brunswick to the northeast. Maine is the northernmost portion of New England and is the easternmost state in the contiguous United States. It is known for its scenery — its jagged, mostly rocky coastline, its low, rolling mountains, and its heavily forested interior — as well as for its seafood cuisine, especially lobsters and clams. The original inhabitants of the territory that is now Maine were Algonquian-speaking peoples. The first European settlement in Maine was in 1604 by a French party. The first English settlement in Maine, the short-lived Popham Colony, was established by the Plymouth Company in 1607. A number of English settlements were established along the coast of Maine in the 1620s, although the rugged climate, deprivations, and conflict with the local peoples wiped out many of them over the years. As Maine entered the 18th century, only a half dozen European settlements still survived. Patriot and British forces contended for Maine's territory during the American Revolution and the War of 1812. Maine was an exclave of Massachusetts until 1820, when as a result of the growing population and a political agreement regarding slavery, it became the 23rd state on March 15 under the Missouri Compromise. Maine is the only U.S. state to have a name that is one syllable long, and the only state which borders exactly one other state. The original inhabitants of the territory that is now Maine were Algonquian-speaking Wabanaki peoples including the Abenaki, Passamaquoddy, and Penobscots. The first European settlement in Maine was in 1604 by a French party that included Samuel de Champlain, the noted explorer. The French named the entire area, including the portion that later became the State of Maine, Acadia. The first English settlement in Maine was established by the Plymouth Company at Popham in 1607, the same year as the settlement at Jamestown, Virginia. Both colonies were predated by the Roanoke Colony by 22 years. Because the Popham Colony did not survive the harsh Maine winters and the Roanoke Colony was lost, Jamestown enjoys the distinction of being regarded as America's first permanent English-speaking settlement. The coastal areas of western Maine first became the Province of Maine in a 1622 land patent. Eastern Maine north of the Kennebec River was more sparsely settled and was known in the 17th century as the Territory of Sagadahock. A second settlement was attempted at a place called York, now Portland, in 1623 by English explorer and naval Captain Christopher Levett, granted 6,000-acres by King Charles I of England.[14] That settlement also failed. The province within its current boundaries became part of Massachusetts Bay Colony in 1652. Maine was much fought over by the French and English during the 17th and early 18th centuries. After the defeat of the French in the 1740s, the territory from the Penobscot River east fell under the nominal authority of the Province of Nova Scotia, and together with present day New Brunswick formed the Nova Scotia county of Sunbury, with its court of general sessions at Campobello. American and British forces contended for Maine's territory during the American Revolution and the War of 1812, and British forces occupied eastern Maine in both conflicts.[15] The treaty concluding revolution was ambiguous about Maine's boundary with British North America. The territory of Maine was confirmed as part of Massachusetts when the United States was formed, although the final border with British territory was not established until the Webster-Ashburton Treaty of 1842. Because it was physically separated from the rest of Massachusetts and was growing in population at a rapid rate, Maine became the 23rd state on March 15, 1820 through the Missouri Compromise. This compromise allowed admitting both Maine and Missouri (in 1821) into the union while keeping a balance between slave and free states.[16] Maine's original capital was Portland, the largest city in Maine, until it was moved to Augusta in 1832 to make it more central within the state. Four U.S. Navy ships have been named USS Maine in honor of the state. As of 2008, Maine has an estimated population of 1,321,504, which is an increase of 6,520, or 0.5%, from the prior year and an increase of 46,582, or 3.7%, since the year 2000. This includes a natural increase since the last census of 6,413 people (that is 71,276 births minus 64,863 deaths) and an increase due to net migration of 41,808 people into the state. Immigration from outside the United States resulted in a net increase of 5,004 people, and migration within the country produced a net increase of 36,804 people. The population density of the state is 41.3 people per square mile. Maine is a very popular tourist destination, but it also experiences harsh winters, and consequently, the great temporary influx of visitors occurs during the warmer months. Many of these visitors establish an alternate secondary residence in Maine during the warm months and then depart for their primary residence in the off-season. These are the summer people of Maine lore. Official census figures normally count a person as a resident only once, at the place of the primary home. Therefore, there are some situations in which official census figures could be misleading for Maine.[citation needed] For example, some communities may have a much larger seasonal retail sector than their official, small population figure would imply. The mean population center of Maine is located in Kennebec County, in or near the town of Mount Vernon.[17] The Greater Portland metropolitan area is the most densely populated with nearly 20% of Maine's population.[18] As explained in detail under "Geography", there are large tracts of uninhabited land in some remote parts of the interior.
