The Treaty of Frankfurt ended the Franco-Prussian war and marked the entry of a newly unified Germany which was dominated by the empires of England and France for a long time. This treaty made France pay them an indemnity of 5 billion Francs and kept an army in France until it had been paid. Because of this, France surrendered Strasburg, Alsace and part of Lorraine to Bismark.
Alsace and Lorraine
France because of the Treaty of Versailles after WW I
Prior to World War 1, Alsace was part of the German Empire. The Treaty of Versailes reverts Alsace back under France's control in June of 1919.
As per the Treaty of Versailles, Alsace-Lorraine was guaranteed a plebiscite which the French did not honor, instead outright annexing the territory. Germany later defeated France and occupied (but did not annex) Alsace-Lorraine during World War 2.
The provinces of Alsace and Lorraine were returned to France following World War I. It was done as part of the Treaty of Versailles in order to punish Germany.
France wanted Alsace-Lorraine back, as she had lost them during the 1870 Franco-Prussian War. The French Third Republic regained the territories when it sent troops to support an uprising there against the Germans in November 1918. The return of the Alsace-Lorraine region to French rule was formally recognized by the Treaty of Versailles.
Alsace-Lorraine & the extension to the west bank of the Rhine River
It was a piece of German land which was taken from them under the treaty of verailles in ww1 and they took it back later in ww2
After the Versailles Treaty was signed, it stated that the entire war was the fault of Germany. The treaty had also limited all of Germany's military, as well as creating the country of Poland and giving Alsace-Lorraine (French region) back to France.
As a result of France's defeat in the Franco-Prussian War of 1870, the peace treaty saw France lose territory. The treaty made France give up Alsace and part of Lorraine.
A dog from Alsace, or anything else from Alsace, is called an Alsatian.
