History and Facts of Maine Counties

Maine Counties – The District of Maine (Part of Massachusetts) was organized on 1778. The State of Maine was created as the 16rd state on March 15, 1820. States bordering Maine are New Hampshire in the west and Canada to the north. It has 16 Counties.

Before statehood, Maine was officially part of the state of Massachusetts and was called the District of Maine. Maine was granted statehood on March 15, 1820 as part of the Missouri Compromise. Nine of the sixteen counties had their borders defined while Maine was still part of Massachusetts, and hence are older than the state itself.
