Have there been any efforts by the countries of Europe to restore their monarchies?

Question

Have there been any effort, polls, referendum in Europe (especially Eastern ex-communist countries) to restore deposed monarchies, like in Romania, Bulgaria, Serbia, etc.? Most Monarchies were deposed of because of communist regimes, Nazi occupation or military dictatorships rather than the will of the people (correct me if I am wrong).

Answer 1

To answer your question you need a book. Anyhow just to mention one example, after II World War in Italy they had a referendum, Republic or Monarchy and only by few votes Republic won.
