Why was Germany required to pay reparation for the war?

Germany was required to pay reparations after World War I primarily due to the Treaty of Versailles, which held the country responsible for the war. The Allies sought to compensate for the extensive destruction and loss of life caused by the conflict, and reparations were intended to punish Germany and weaken its economy. This financial burden aimed to prevent future military aggression, although it ultimately contributed to economic hardship and political instability in Germany, paving the way for the rise of extremist movements.
