I want to know the answer to the following question:
Why did a regional referendum in 1996 to merge Berlin with surrounding Brandenburg fail?
All the background I'm provided with is that "German reunification in 1990, in which the German Democratic Republic (East Germany) ascended into the Federal Republic, resulted in the addition of the re-established eastern states of Brandenburg, Mecklenburg-West Pomerania (in German Mecklenburg-Vorpommern), Saxony (Sachsen), Saxony-Anhalt (Sachsen-Anhalt), and Thuringia (Thüringen), as well as the reunification of West and East Berlin into Berlin and its establishment as a full and equal state.". Is that enough to answer the question?
Answer: no
