1918 – 1920 · and the last two owners A magnate house inside a republicMagnátsky dom v republike

In 1918 Austria-Hungary broke up and Betliar found itself in Czechoslovakia, confirmed by the Treaty of Trianon in 1920. The family kept the house through the interwar republic: Gejza Andrássy (1856–1938), politician and businessman, and after him Emanuel Andrássy the younger (1892–1953), the last owner. Everything around them changed. There was a new state with a land reform aimed squarely at estates of this size, a Gemer iron industry that had lost the imperial market it grew up serving, and an aristocracy whose titles the republic no longer recognised. The house went on being lived in, and it went on accumulating, which is the only reason there was anything left to save in 1945.V roku 1918 sa Rakúsko-Uhorsko rozpadlo a Betliar sa ocitol v Česko-Slovensku, čo potvrdila Trianonská zmluva v roku 1920. Rod si dom udržal cez celú medzivojnovú republiku: Gejza Andráši (1856 – 1938), politik a podnikateľ, a po ňom Emanuel Andráši mladší (1892 – 1953), posledný majiteľ. Všetko naokolo sa však zmenilo. Prišiel nový štát s pozemkovou reformou mierenou práve na panstvá tejto veľkosti, gemerské železiarstvo stratilo cisársky trh, pre ktorý vyrástlo, a šľachte republika prestala uznávať tituly. V dome sa naďalej bývalo a naďalej sa v ňom hromadilo — a len preto bolo v roku 1945 čo zachraňovať.
