What Is The "Potential" Referendum For Creating The German Unification Treaty Of 1990 Proclaiming That The German Democratic Republic Will Dissolved And Integrating Reestablished Constituent Federated States Into The Federal Republic Of Germany Then Re-Merged And Re-Created The Modern Federal Republic Of Germany And Regaining Germany's Full Sovereign State/Country Status.

The process you're referring to is the reunification of Germany in 1990. The "Potential Referendum" you mention wasn't a direct referendum but rather a series of negotiations and agreements between the Federal Republic of Germany (West Germany) and the German Democratic Republic (East Germany). This process led to the creation of the Unification Treaty, which paved the way for the dissolution of the German Democratic Republic and the integration of its states into the Federal Republic of Germany.

The Basic Law for the Federal Republic of Germany (Grundgesetz) was extended to cover the territory of the former German Democratic Republic, and this reunification officially took place on October 3, 1990. The process was a historical milestone, marking the end of the division of Germany that had persisted since the end of World War II.
