Treaty of Trianon
The Treaty of Trianon was an agreement following World War I, which was supposed to regulate the post-war situation of the Hungarian state. It was signed on June 4, 1920, at the Grand Trianon Palace at Versailles, France, reducing the size and population of Hungary by about two thirds.
Hungary lost most of its peripheral territories:
- Transylvania, the adjoing plains (the Partium), and parts of the Banat (including Timisoara) went to Romania
- Czechoslovakia received Slovakia and Ruthenia
- Croatia, Slavonia, and the western section of the Banat (Vojvodina) joined the newly formed Kingdom of Serbs, Croats and Slovenes
- Austria was awarded the Burgenland; the city of Sopron and surrounding areas were returned to Hungary after a plebiscite held in 1921
Due to the treaty, Hungary lost the access to the sea it had through Croatia since 1102. Further provisions stated that its army be limited to 35,000 men, or that no railway shall be built with more than one track.
Hungary recovered some of the lost territories at the wake of World War II in 1939-1940, mainly upon the Agreements of Vienna, but the new boundaries agreed on at the Treaty of Paris in 1947 were nearly indentical with those of 1920.
