In 1918, after the collapse of the monarchic union of Austria-Hungary, and after the disarmament of the local police, the Međimurje region fell into civil disorder. The People's Council of Slovenes, Croats and Serbs in Zagreb sent hastily assembled troops, which crossed the river Mura and fought all the way to Dolnja Lendava, where they met resistance. Troops commanded by Slavko Kvaternik finally forced the Hungarian troops to abandon the region. On 9 January 1919, Međimurje joined to the newly created Kingdom of Serbs, Croats and Slovenes (later known as Yugoslavia).
