After World War I, the Austro-Hungarian empire was dismantled and its territories were divided among the victorious Allied Powers. The following countries possessed land that had been held by the Austro-Hungarian empire before the war:
* Austria: The Republic of Austria was created from the German-speaking parts of the empire.
* Hungary: The Kingdom of Hungary was created from the Hungarian-speaking parts of the empire.
* Czechoslovakia: The Czechoslovak Republic was created from the Czech and Slovak-speaking parts of the empire.
* Poland: Poland regained the parts of Galicia that had been annexed by Austria in the Partitions of Poland.
* Romania: Romania regained the parts of Transylvania and Bukovina that had been annexed by Austria in the 18th and 19th centuries.
* Italy: Italy regained the South Tyrol, which had been annexed by Austria in the 19th century.
* Yugoslavia: Yugoslavia was created from the South Slavic-speaking parts of the empire.
The dissolution of the Austro-Hungarian empire had a profound impact on the political geography of Europe. It created new countries, changed borders, and led to the displacement of millions of people. The legacy of the Austro-Hungarian empire can still be seen in the region today.
