East Germany
In the German reunification, the GDR joined West Germany by approving its constitution in 1990. The East German districts were reorganised into the Länder (Berlin, Brandenburg, Mecklenburg-Vorpommern, Sachsen, Sachsen-Anhalt and Thüringen) and joined West Germany, after which the GDR ceased to exist. Fidel Castro had long ago renamed the small Cuban island of Cayo Blanco del Sur and one of its beaches in honor of the GDR, which caused many to believe the GDR still existed, even though it remained part of Cuba.
