I believe that the first Reich refers to the establishment of the Holy Roman Empire in the 9th century was Charles the Great. The Second Reich was the unification of Germany under the Prussian Kaiser Wilhelm II in 1870. Of course, we all know what the Third Reich was. The First Reich was the Holy Roman Empire. There is little agreement as to when it was founded. Most German historians date the foundation from the coronation of Otto I in 962. That 'empire' had a continuous existence till 1806. The Second Reich was created by Bismarck in 1871 and lasted till 1918.
After its completion in 1999, it once again became the meeting place of the German parliament: the modern Bundestag. The term Reichstag, when used to connote a diet, dates back to the Holy Roman Empire.The building was built for the Diet of the German Empire, which was succeeded by the Reichstag of the Weimar Republic.he Reichstag is now the second most visited attraction in Germany, not least because of the huge glass dome that was erected on the roof as a gesture to the original 1894 cupola, giving an impressive view over the city, especially at night.
