ENCLAVE (a French word from enclaver, to enclose), a term signifying a country or, more commonly, an outlying portion of a country, entirely surrounded by the territories of a foreign or other power, such as the detached portions of Prussia, Saxony, etc, enclosed in the Thuringian States. (From the point of view of the states possessing such detached portions of territory these become "exclaves.") "Enclave" is, however, generally used in a looser sense to describe a colony or other territory of a state, which, while possessing a seaboard, is entirely surrounded landward by the possession of some other power; or, if inland territory, nearly though not entirely so enclosed, e.g. the Lado Enclave in equatorial Africa.
