The idea of a united Germany was born during the revolutionary movements of 1848 (movements present throughout Europe). Unity was necessary to free the economic development blocked by too many internal borders and customs. Before the Unification there were different peoples:
- Saxons
- Babares
- Swabians
- Frisians
- Prussians etc.
The ceremony of the Constitution of the new Germany was celebrated on January 18, 1871 in the royal palace of Versailles, symbol of the French monarchy. In addition to the military defeat, it was a great humiliation for the French, so much so that, 50 years later at the end of the great war, the French demanded that the armistice between victorious France and defeated Germany be signed in the same French royal palace.
If in 1870 France, which had lost the war (against Prussia) had to cede the two border regions of Alsace and Lorraine, in 1919 Germany had to return the same two regions to France
