How was the map of Europe re-drawn after World War 1?

Answer 1

With the collapse of Germany, Austria-Hungary, Russia, and the Ottoman Empire, the map of Europe had to be almost entirely redrawn after the War. In place of the old empires, new nations representing different identities were born.
Among other means, WW1 changed the map of Europe through the disbanding of empires (e.g. Austro-Hungarian), loss of territory (e.g. Germany gave up territory to Poland and Czechoslovakia), the formation of new countries (e.g. Austria, Hungary, Yugoslavia, Czechoslovakia) and the transfer in ownership of colonies (e.g. Germany's and Turkey's) to the League of Nations.
