A municipality is usually an urban administrative division having corporate status and usually powers of self-government or jurisdiction. The term municipality is also used to mean the governing, ruling body of a municipality.A municipality is a general-purpose administrative subdivision, as opposed to a special-purpose district. The term is derived from French "municipalité" and Latin "municipalis".The English word "Municipality" derives from the Latin social contract "municipium", meaning duty holders, referring to the Latin communities that supplied Rome with troops in exchange for their own incorporation into the Roman state (granting Roman citizenship to the inhabitants) while permitting the communities to retain their own local governments (a limited autonomy).
In various countries, municipalities are sometimes referred to as "communes", from Latin, notably in Romance languages such as French commune (Benin, France), Italian comune, Romanian comună, and Spanish comuna (Chile), and in Germanic languages such as German Kommune, Swedish kommun, and Norwegian/Danish kommune. Other terms include Spanish ayuntamiento, and municipalidad (cognate to "municipality") and Polish gmina.In Australia, the term local government area (LGA) is used in place of the generic municipality. Here, the "LGA Structure covers only incorporated areas of Australia. Incorporated areas are legally designated parts of states and territories over which incorporated local governing bodies have responsibility."
