Trianon Treaty Day
The Trianon Treaty Day is a holiday in Romania celebrated every 4 June to commemorate the signing of the Treaty of Trianon in 1920. The holiday was first proposed in 2015 by the Romanian politician Titus Corlățean and subsequently promulgated on 18 November 2020 by President Klaus Iohannis.
Background
After the collapse of Austria-Hungary at the end of World War I, the Romanian Army took control of Transylvania starting from November 1918 as the Hungarian–Romanian War was ongoing.The Romanian National Assembly proclaimed the Union of Transylvania with Romania on 1 December 1918. In the assembly, 1,228 delegates present declared their intention for Transylvania, the Körös region, the Banat, and Máramaros – altogether 26 historic counties of the Kingdom of Hungary – to unite with the Kingdom of Romania. Although the decision of Romanians was the result of a unilateral resolution, it completely deprived the Hungarians along with the other ethnic groups of Transylvania of their right to self-determination. The Székelys at the end of November, and the Hungarians of Kolozsvár made also an assembly on 2 December and declared that they did not wish to belong to Romania, despite the Romanian occupation continued as far as Western Hungary.
The Treaty of Trianon was a treaty signed on 4 June 1920 between Hungary and the Allies. As a result, Transylvania, as well as parts of Banat, Crișana and Maramureș, were officially allocated to Romania. Hungary also lost territories to Austria, Czechoslovakia, the Kingdom of Serbs, Croats and Slovenes and Poland as a consequence of it. The Treaty of Trianon drew a border that placed about 1,658,045 Hungarians under Romanian rule, although the territory granted was smaller than what Romania had originally demanded.
