Explanation:

The Treaty of Versailles was the treaty prescribed to be signed by the Allied powers and Germany. It was intended to be a peace document that was to be singed after the first World War. The treaty demanded the compensation for all the losses that the civilians of the Allied nation had faced during the War.
