Trianon syndrome

The Treaty of Trianon was a peace treaty signed after World War I through which the Kingdom of Hungary lost over two-thirds of its land to Austria, Czechoslovakia, Italy, the Kingdom of Serbs, Croats and Slovenes (later renamed to Yugoslavia), Poland and Romania.

[1][2][3] The Trianon syndrome may also be considered as existing in some of these countries in the form of worry about Hungarian revisionism.

[4] The Trianon syndrome had great relevance in Hungary from 1920 to 1945, after which the country was occupied by the Soviet Union, and re-emerged following the end of Soviet influence in 1990, with current Hungarian society being divided between those who remain resentful about the Treaty of Trianon and those who prefer to forget it.

[5] Hungarian media has also suggested that the Trianon syndrome is found in Romania as well, among politicians and nationalist intellectuals.

Furthermore, a Romanian politician, Titus Corlățean, pushed for the declaration of 4 June as the Trianon Treaty Day in Romania to celebrate the union of Transylvania with the country.
