Concept note-1: -This provision effectively prevented many German industries from selling their goods in foreign markets. In order to pay its debts for World War I, as dictated by the Versailles Treaty, Germany engaged in a tremendous hyperinflation of its currency, printing paper marks until, by 1923, they became utterly worthless.
Concept note-2: -Germany lost the most land as a result of World War I. As a result of the Treaty of Versailles in 1919, Germany was stripped of 13% of its European territory. All of the land Germany had acquired outside of Europe was lost.
Concept note-3: -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.
Concept note-4: -The Ottoman Empire officially ended in 1922 when the title of Ottoman Sultan was eliminated. Turkey was declared a republic on October 29, 1923, when Mustafa Kemal Atatürk (1881-1938), an army officer, founded the independent Republic of Turkey.
