Buuxi weedha soo socota: Sanadkii 1523, George of Schellenberg wuxuu ku qasbanaaday inuu ka iibiyo Krnov Hohenzollern margrave George of Brandenburg-Ansbach, oo ku tiirsanaan kara dhaxalka Hungary ee xaaskiisa Beatrice de Frangepan, carmalka Matthias Corvinus. Laga soo bilaabo 1532 margrave wuxuu xukumay dhammaan Upper Silesia, markii uu sidoo kale dhaxlay Duchy of Opole iyo Racibórz oo ka yimid duke Piast Jan II the Good. Wuxuu dib u dhisay qalcaddii Krnov wuxuuna soo bandhigay dib-u-habeyntii Protestant-ka ee Silesia, isagoo ka saaray Knights-ka Teutonic, Franciscans iyo Minorites. Awoodda sii kordheysa ee Protestant House of Hohenzollern ee dhulalka boqortooyada Silesian waxaa si shaki leh u eegay Ferdinand I ee Habsburg, Boqorka Bohemian tan iyo 1526. Si kastaba ha noqotee, George iyo sidoo kale wiilkiisa Margrave George Frederick, oo xukumay laga bilaabo 1543, waxay awoodeen inay hayaan duchy. Khilaafka ayaa sii xumaaday markii George Frederick uu geeriyooday ilmo la'aan sanadkii 1603 wuxuuna Krnov u dhaxalsiiyey adeerkiis Elector Joachim III Frederick ee Brandenburg, kaasoo siiyay wiilkiisa Johann Georg sanadkii 1607. Boqoradii Habsburg waxay u arkeen duqnimada inay tahay hanti ay dib u soo celiyaan kadib kacdoonkii Bohemian iyo 1620
Dagaalkii Buurta Cad Boqor Ferdinand II ayaa la wareegay hantidii Hohenzollern ee dhulka Bohemian. Ferdinand taageere daacad ah Amiir Karl I ee Liechtenstein, Duke of Opava tan iyo 1613, wuxuu helay Krnov. Labada dukadoodba waxaa la isku daray 1623 waxaana lagu soo rogay Dib-u-habeyn.
