Treaty of Trianon
Hungary's postwar partition
The Treaty of Trianon was a 1920 peace agreement that ended World War I between the Allied powers and Hungary.
It dismembered the Kingdom of Hungary, transferring two-thirds of its territory and one-third of ethnic Hungarians to neighboring states—Romania, Czechoslovakia, and Yugoslavia.
The treaty remains a source of Hungarian nationalist grievance: Trianon still shapes Hungarian politics a century later.
