A municipal corporation is the legal term for a local governing body, including (but not necessarily limited to) cities, counties, towns, townships, charter townships, villages, and boroughs. The term can also be used to describe municipally-owned enterprises.
Municipal corporations are by definition incorporated, in contrast to unincorporated areas.
Municipal incorporation occurs when such municipalities become self-governing entities under the laws of the state or province in which they are located. Often, this event is marked by the award or declaration of a municipal charter. A city charter or town charter (generically, municipal charter) is a legal document establishing a municipality such as a city or town. The concept developed in Europe during the Middle Ages and is considered to be a municipal version of a constitution. With the notable exceptions of the City of London Corporation and the Laugharne Corporation, the term has fallen out of favour in the United Kingdom, but the concept remains central to local government in the United Kingdom, as well as former British colonies such as Canada and India.
In Canada charters are granted by provincial authorities.
