Which treaty allowed the nations of france, denmark, and the czech republic to acquire land from germany?

The treaty that allowed the nations of France, Denmark, and the Czech Republic to acquire land from Germany was the Treaty of Versailles.

Explanation:

The Treaty of Versailles was a peace treaty that was signed in the city of Versailles at the end of World War I by more than fifty countries. This treaty officially ended with the state of war between Germany and the Allies of World War I. It was signed on June 28, 1919, exactly five years after the Sarajevo bombing in which Archduke Franz Ferdinand was killed, the direct cause of World War I.

Because of the treaty, Germany considerably reduced its European territory from 540,766 km² (1910) before the war, to 468,787 km² (1925) after the war. In addition, it was forced to give up all its colonial empire, which was divided among the winning nations (mainly between the United Kingdom and France).

Thanks to the treaty, Denmark received 3,984 km², France obtained 73,533 km², and Czechoslovakia separated from the Austro-Hungarian Empire.
