West Berlin was a political enclave which comprised the western part of Berlin from 1948 until 1990, during the Cold War. Although West Berlin lacked any sovereignty and was under military occupation until German reunification in 1990, the territory was claimed by the Federal Republic of Germany (FRG), despite being entirely surrounded by East Germany (GDR). The legality of this claim was contested by the Soviet Union and other Eastern Bloc countries. However, West Berlin de facto aligned itself politically with the FRG from May 1949 and was thereafter treated as a de facto city-state of that country. After 1949, it was directly or indirectly represented in the institutions of the FRG, and most of its residents were citizens of the FRG.

An enclave is a territory that is entirely surrounded by the territory of only one other state or entity. Such territory can be a small territory as part of a larger one. Enclaves may also exist within territorial waters. Enclave is sometimes used improperly to denote a territory that is only partly surrounded by another state. Many enclaves are also exclaves, but some are not, for example Vatican City and San Marino and Lesotho are completely enclaved sovereign states.
