Which countries and empires shown on the prewar map do not appear and the post war map?

Countries and empires such as the Austro-Hungarian Empire, the Ottoman Empire, and the German Empire do not appear on the post-war map following World War I. The dissolution of these empires led to the emergence of new nation-states, such as Czechoslovakia and Yugoslavia, which were not present in the pre-war map. Additionally, significant territorial changes occurred, with countries like Poland being re-established after a long absence.
