Stephen II Csák

[4] Stephen and his descendants remained landowners near the ancient estate of the genus, Csákvár, while his cousins, Matthew III and Csák acquired possessions in the north-western counties of the Kingdom of Hungary, where later Matthew III, as the most powerful oligarch, ruled de facto independently of the king and usurped royal prerogatives on his realm.

[5] Stephen also tried to establish a dominion independently of the central power, expanding his influence over the territories that surrounded his possessions and centre, the Csókakő Castle.

Andrew III of Hungary called him a "powerful tyrant of the country" (Latin: fortissimus tirannus regni nostri) in 1295, when Stephen captured and imprisoned the members of the Süttői family from the kindred Szák in Esztergom County.

In September 1302, Stephen led Charles' army to occupy Buda Castle, Wenceslaus' residence; however the siege ended in failure, the pro-Přemyslid lord Ivan Kőszegi successfully defended the capital.

[10] In August 1304, Stephen was among the barons who signed the Treaty of Pressburg (Pozsony; today Bratislava, Slovakia) between Charles I and Rudolf III, Duke of Austria and Styria, against Wenceslaus.

His sons, Mark II and Peter III, attended the second coronation of Charles I on 15 June 1309, continuing their father's political orientation.
