Pozsony County
Matthew II established his centre at Tapolcsány (today: "Podhradie, Slovakia"), where a stone castle was built and strengthened. He did not donate his estates in Nyitra County to the Church, those remained in the clan. Perhaps he had also estates or vassals in Pozsony County, maybe one of them was Thomas Hont-Pázmány, for whom Matthew II, as palatine, acted to the Archdiocese of Esztergom, in connection with a payment of a loss. The expansion in Pozsony County caused conflicts between the Csák clan and the Kőszegi family, which had long been a landowner in the county.
