text: The borders of many states were completely redrawn, and the new Kingdom of Serbs, Croats, and Slovenes, later Yugoslavia, was created. Both Austria-Hungary and the Ottoman Empire were formally dissolved. As a result, the balance of power, economic relations, and ethnic divisions were completely altered.
  Some important territorial changes include:
  The addition of Transylvania and Eastern Banat to Romania
  The incorporation of Serbia, Montenegro, Slavonia, Croatia, Vojvodina, Carniola, part of Styria, most of Dalmatia, and Bosnia and Herzegovina into the Kingdom of Serbs, Croats, and Slovenes.
  Istria, Zadar, and Trieste became part of Italy,
  Between World War I and World War II, in order to create nation-states the following population movements were seen:
  In the interwar period, almost 1.5 million Greeks were removed from Turkey; almost 700,000 Turks removed from Greece
  The 1919 Treaty of Neuilly-sur-Seine provided for the reciprocal emigration of ethnic minorities between Greece and Bulgaria. Between 92,000 and 102,000 Bulgarians were removed from Greece; 35,000 Greeks were removed from Bulgaria. Although no agreement on exchange of population between Bulgaria and the Kingdom of Serbs, Croats, and Slovenes was ever reached because of the latter's adamant refusal to recognise any Bulgarian minority in its eastern regions, the number of refugees from Macedonia and Eastern Serbia to Bulgaria also exceeded 100,000. Between the two world wars, some 67,000 Turks emigrated from Bulgaria to Turkey on basis of bilateral agreements.
