Treaty of Trianon
4 June 1920
The 1920 peace treaty between the Allies and Hungary, signed at the Grand Trianon near Versailles, that set Hungary's new borders after the war Kun's regime had fought to resist.
The treaty set the territorial losses that Kun's nationalist-revolutionary war of 1919 had aimed to prevent.

About this source
What it is
This is the Treaty of Trianon, a peace settlement signed at the Grand Trianon at Versailles on 4 June 1920. It was prepared at the Paris Peace Conference and formally ended World War I between most of the Allies and the Kingdom of Hungary. The copy shown here is a printed British edition published by His Majesty's Stationery Office, presented to Parliament as Treaty Series No. 10 (1920).
Why it matters
The treaty fixed the territorial losses that had fuelled the nationalist-revolutionary war of 1919, in which Béla Kun led the Hungarian Soviet Republic. Hungary lost about 72 percent of its pre-war territory, and about 3.3 million Hungarians came to live in neighbouring states. The treaty was dictated by the Allies rather than negotiated, and Hungarian delegates signed under protest. Its consequences caused lasting resentment in Hungary.
Look closer
- Why did the Allies refuse plebiscites for the new borders, and how did Hungarian diplomats read the Millerand letter?
- Who gained from the treaty, and whose voices are missing from a document written by the victors?
- How does a printed British government copy change the way students might read a document about Hungary?
