Local government is a form of public administration which in a majority of contexts, exists as the lowest tier of administration within a given state. The term is used to contrast with offices at state level, which are referred to as the central government, national government, or (where appropriate) federal government. Local governments generally act within powers delegated to them by legislation or directives of the higher level of government. In primitive societies the lowest level of local government is the village headman or tribal chief. Federal states such as the United States have two levels of government above the local level: the governments of the fifty states and the federal national government whose relations are governed by the constitution of the United States. Local government in the United States originated in the colonial period and has been modified since then: the highest level of local government is at county level.^{[citation needed]}

The question of Municipal Autonomy is a key question of public administration and governance. The institutions of local government vary greatly between countries, and even where similar arrangements exist, the terminology often varies. Common names for local government entities include state, province, region, department, county, prefecture, district, city, township, town, borough, parish, municipality, shire and village.
