On the Prekmurje Reunification Day, Slovenia marks the events which led to the reunification of the Prekmurje Slovenes with the rest of Slovenia, ending 900 years of Hungarian rule. After the end of the first world war, as part of the 1919 Versailles Peace Treaty, it was decided that the region come under the authority of the Kingdom of Serbs, Croats and Slovenes. The Yugoslav army thus took control of the territory on August 12th, 1919 and five days later, on August 17th, gave the command over it to the civil authorities. It was decided that August 17th, the day when the civil administrator took control of the region from the army at a massive people's rally in Beltinci, was to be the official date of the reunification. A part of Slovenes still lives in the area along the river Raba and thus, according to the before mentioned peace treaty, remain in Hungary.

August 17 became a national holiday in September 2005, with the amendment to the law on public holidays, which was adopted by the National Assembly.
