He personally assisted King Charles I against the rebelling Kőszegi family in the counties of Baranya and Tolna from April to July 1316, and against the powerful Matthew III Csák in the siege of Komárom (Komárno, Slovakia) in October 1317.
Here the archbishop of Esztergom and his suffragan bishops appointed Ladislaus Kórógyi to express all their grievances, including the taxation of Church properties, to the monarch.
Ladislaus Kórógyi was also often appointed by the popes to proceed on behalf of the Holy See with King Charles I who frequently took advantage of vacancies in Church offices in order to seize their income for himself.
No doubt, Bishop Ladislaus was one of the authors of an anonymous letter sent in 1338 by Hungarian prelates to the pope which listed their complaints against King Charles I.
Although Bishop Ladislaus confirmed the exemption from the tithes of the monastery of Saint James Hill at Pécs, he disputed (in vain) the same status of the Paulines and the Knights Hospitaller in his diocese.
