Explanation:

Germany had formally surrendered on November 11, 1918, and all nations had agreed to stop fighting while the terms of peace were negotiated. On June 28, 1919, Germany and the Allied Nations (including Britain, France, Italy and Russia) signed the Treaty of Versailles, formally ending the war.

World War I was one of the great watersheds of 20th-century geopolitical history. It led to the fall of four great imperial dynasties (in Germany, Russia, Austria-Hungary, and Turkey), resulted in the Bolshevik Revolution in Russia, and, in its destabilization of European society, laid the groundwork for World War II.
