 As Maribor was now firmly in the hands of the Slovenian forces and surrounded completely by Slovenian territory; the city had been recognised as part of the Kingdom of Serbs, Croats and Slovenes without a plebiscite in the Treaty of Saint-Germain of 10 September 1919 between the victors and German Austria.For his actions in Maribor and later in the Austro-Slovene conflict in Carinthia, Rudolf Maister is today considered a Slovenian national hero.After 1918, most of Maribor's Austrian Germans left the Kingdom of Serbs, Croats and Slovenes for Austria.
