Which region did Germany lose as a result of the Treaty of Versailles?

The Treaty of Versailles, signed in 1919 after World War I, resulted in significant territorial losses for Germany as part of the peace settlement. One of the most notable regions that Germany lost was Alsace-Lorraine. This region, located on the border between France and Germany, was originally annexed by Germany in 1871 following the Franco-Prussian War.

The return of Alsace-Lorraine to France was a significant point in the treaty, reflecting France's desire to regain territories lost in the previous conflict and to re-establish its national boundaries. The loss of this region was particularly symbolic as it not only represented a return of land but also a restoration of national pride for France. In the context of the post-war settlement, Alsace-Lorraine became a clear example of the punitive measures taken against Germany, affecting its national integrity and contributing to the sense of humiliation that fueled political unrest in the years that followed.
