Матуш Чак
Matthew (II) from the kindred Csák (; ; ; "c". 1235 – 1283 or 1284) was a powerful Hungarian baron, landowner and military leader, who held several secular positions during the reign of kings Béla IV, Stephen V and Ladislaus IV. He was the first notable member of the Trencsén branch of the "gens" ("clan") Csák. His nephew and heir was the oligarch Matthew III Csák, who, based on his uncles' acquisitions, became the "de facto" ruler of his domain independently of the king and usurped royal prerogatives on his territories.
