High Quality Content by WIKIPEDIA articles! The new federal states of Germany (German: Neue Bundesländer) are the five re-established states in the former German Democratic Republic that acceded to the Federal Republic of Germany with its 10 states upon German reunification on 3 October 1990. The new states, which had been abolished by the East German government in 1952 and were re-established in 1990, are Brandenburg, Mecklenburg-Vorpommern, Saxony, Saxony-Anhalt and Thuringia. The state of Berlin, the result of a merger between East and West Berlin, is usually not considered one of the new Länder, although many of its residents are former East Germans.
