Which 1919 treaty imposed peace terms on Germany after World War I?

The Treaty of Versailles imposed peace terms on Germany after World War I.

Signed on 28 June 1919 in the Hall of Mirrors at the Palace of Versailles, the treaty formally ended the state of war between Germany and the Allied Powers. It required Germany to accept responsibility for wartime damage, make reparations, reduce its armed forces and surrender territory.

The agreement also created the League of Nations framework, although the United States never ratified the treaty and did not join the League. Versailles was one of several postwar settlements: the Treaty of Saint-Germain addressed Austria, and the Treaty of Trianon addressed Hungary. Its punitive provisions and political consequences remained controversial and are frequently discussed as part of the unstable conditions that preceded World War II.
