Treaty of Trianon
1920 peace agreement formally ending World War I between most of the Allies of World War I and the Kingdom of Hungary

The Treaty of Trianon (French: Traité de Trianon; Hungarian: Trianoni békediktátum; Italian: Trattato del Trianon; Romanian: Tratatul de la Trianon), often referred to in Hungary as the Peace Dictate of Trianon or Dictate of Trianon, was prepared at the Paris Peace Conference. It was signed in the Grand Trianon at Versailles on 4 June 1920, and formally terminated World War I between most of the Allies of World War I and the Kingdom of Hungary. The treaty is known for the territorial changes imposed on Hungary and recognition of its new borders after World War I.
As part of the Austro-Hungarian Empire, Hungary had been involved in World War I since August 1914. After its allies signed armistices with the Entente, the political elite in Budapest also opted to end the war. On 31 October 1918, the Budapest government declared independence of Hungary from Austria and began peace talks with the Allies which led to an armistice on 13 November 1918. Hungary demobilised its army and granted the Allies the right to occupy the country's south and east until a peace treaty was signed. In December 1918, Budapest allowed Czechoslovak troops to occupy the country's north. In exchange, Budapest hoped to reopen trade and a supply of coal. Despite the end of hostilities, Hungary's neighbours Czechoslovakia, Romania, and The Kingdom of Serbs, Croats, and Slovenes blockaded the country, preventing it from importing food, fuel, and other important goods. Successive Hungarian governments pleaded with the Entente to lift the blockade.

Why this record matters
The phrase “1920 peace agreement formally ending World War I between most of the Allies of World War I and the Kingdom of Hungary” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Sep 9, 2026. The linked authority identifier is Q181902. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1920, 1914 and 1918.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
