The Treaty of Trianon was signed on June 4, 1920 at the Trianon Palace in Versailles, France, between the Allies and Hungary. Under the agreement, Hungary lost two-thirds of the territory, which is divided between Austria, Czechoslovakia, the Kingdom of Serbs, Croats and Slovenes and Romania.
Under the Trianon Treaty, Hungary ceded Burgenland without Sopron to Austria, Transylvania to Romania (Erdelj), Czechoslovakia to Slovakia, and western Banat, Backa, southern Baranya and Medjimurje and Prekmurje to the Kingdom of Serbs, Croats and Slovenes. The treaty imposed war reparations and a drastic downsizing on Hungary.
