Maine is the 12th-smallest by area, the 9th-least populous, the 13th-least densely populated, and the most rural. Bordered by New Hampshire to the west; the Gulf of Maine to the southeast; and the Canadian provinces of New Brunswick and Quebec to the northeast and northwest, respectively.
There is no official reason for the name “Maine,” however it is most probable that it was called after the former French province of Maine by early explorers. Whatever its origins, the name was cemented in stone for English immigrants in 1665, when the English King’s Commissioners ordered that the “Province of Maine” be written in official documents from then on.
