when did france lose alsace and lorraine to germany
Alsace-Lorraine The Imperial Territory of Alsace-Lorraine (German: Reichsland ElsaÃŸ-Lothringen or Elsass-Lothringen) was a territory created by the German Empire in 1871, after it annexed most of Alsace and the Moselle department of Lorraine following its victory in the Franco-Prussian War. The Alsatian part lay in the Rhine Valley on the west bank of the Rhine River and east of the Vosges Mountains. The Lorraine section was in the upper Moselle valley to the north of the Vosges.
French Third Republic The French Third Republic (French: La Troisième République, sometimes written as La IIIe République) was the system of government adopted in France from 1870, when the Second French Empire collapsed, until 1940, when France's defeat by Nazi Germany in World War II led to the formation of the Vichy government in France. It came to an end on 10 July 1940.
