Mancomunidad
Introduction Logo of the  of Cantalapiedra y Las Villas, Province of Salamanca, Spain.In present-day Spain a '''''mancomunidad'''''()is an association of municipalities voluntarily established by some municipalities with the aim of carrying out joint projects or providing common services. A mancomunidad is one of the ''local entities'' defined for the purpose of local government, to which those municipalities may voluntarily delegate some of their functions and powers. There were 1,023 mancommunidades in 2011.
Purpose In general, mancomunidades are aimed at carrying out projects or providing common services.A ''mancomunidad'' has legal personality, and can exist either for a particular period to achieve a concrete goal or can exist indefinitely.A mancomunidad is similar to a comarca, with the difference that ''comarca'' has somewhat different meanings in the various autonomous communities of Spain and ''mancomunidad'' is defined identically throughout the country. The municipalities in a single ''mancomunidad'' need not be coterminous (though they usually are). They are required to set a clear goal, create management bodies distinct from those of the individual municipalities, and provide the ''mancomunidad'' with its own budget.There are a number of natural or historical regions that, despite the strong identity and common goals of their inhabitants, are divided by provincial or even ancient kingdom boundaries. Examples of such regions are Tierra de Campos, Manchuela and Ilercavonia. Such regions or comarcas have often not been able to achieve the necessary legal recognition for their administrative development within the existing provincial or autonomous frameworks. Therefore, their municipalities have resorted to organizing themselves into a mancomunidad.Other groups of municipalities that do not face the problem of borders cutting across their natural region or comarca may form a mancomunidad for economic reasons, to improve local services or in order alleviate some form of historical administrative neglect owing to distance from and lack of communication with current administrative centers.
Other uses The term ''mancomunidad'' and its cognates are also used to translate the English word "commonwealth".
