# Treaty of Trianon The peace treaty signed at the **Grand Trianon palace at Versailles on 4 June 1920** between Hungary and the victorious Allied powers, settling Hungary's borders after the dissolution of Austria-Hungary. It is the single most consequential document in modern Hungarian political life and the grievance engine underneath a century of Hungarian right-wing politics. ## What it did - Reduced the territory of the Kingdom of Hungary by roughly **two-thirds**, and its population by around **three-fifths**. - Transferred Transylvania and part of the Banat to Romania; Slovakia and Carpathian Ruthenia to the new Czechoslovakia; Croatia-Slavonia, the Bácska and most of the Banat to the Kingdom of Serbs, Croats and Slovenes; Burgenland to Austria; small districts to Poland; and Fiume to Italy. - Left roughly **three million ethnic Hungarians** living as national minorities in neighbouring states — the largest single group being in Romania. - Capped the Hungarian army at 35,000 volunteers, banned conscription, and imposed reparations. - Landlocked the country and severed it from most of its industrial base and raw materials. ## Why it kept mattering Interwar Hungary organised itself around revision. Flags flew at half-mast; schoolchildren recited the **Magyar Hiszekegy** creed; the slogan *Nem, nem, soha* — "No, no, never" — was ubiquitous. The pursuit of revision is the direct cause of Hungary's alignment with Nazi Germany, which returned parts of the lost territory in the two Vienna Awards of 1938 and 1940 and took them back again in 1947. After 1989 Trianon returned as a legitimate public subject, and after 2010 it became state policy: - **2010** — parliament designated **4 June** the **Day of National Cohesion**. - **2010** — simplified naturalisation opened Hungarian citizenship to ethnic Hungarians beyond the borders with no residency requirement, adding roughly a million citizens over the following decade. - **2014** — those citizens gained postal voting rights in the party-list half of Hungarian elections, converting a historical claim into an electoral constituency. - **2020** — a centenary "Trianon Monument of National Cohesion" was opened outside parliament, inscribed with the name of every settlement of the pre-1920 kingdom. > [!important] ⭐ Why this page is in a knowledge base about the American right > Trianon is the clearest available case of a **territorial-loss narrative converted into durable governing advantage**. It supplies the same emotional architecture as the [[Lost Cause]] — a nation stabbed in the back, a greatness stolen by outsiders and traitors, a map that is the *real* country — but Hungary went one step further and gave the grievance a franchise. **When a historical wound is being maintained rather than mourned, look for what it is being spent on.** ## See Also - [[Hungarian History Hub]] - [[Viktor Orbán]] · [[Fidesz]] · [[Hungary]] - [[Miklós Horthy]] · [[Arrow Cross Party]] - [[World War I]] · [[Treaty of Versailles]] · [[World War II]] - [[Aggrieved Entitlement]] · [[Lost Cause]] · [[Nationalism]] · [[Ethnonationalism]]
