Matthew I Csák

Matthew (I) from the kindred Csák (;? – 1245/1249) was a powerful Hungarian baron of king Béla IV, the first known member of the Trencsén branch of the gens (clan) Csák. His grandson was the oligarch Matthew III Csák.

Family He was born into the Csák clan from unknown parents, as a result there is an inability to connect the Trencsén branch to the other branches of the clan. In 1235, when he was first mentioned by contemporary records, Matthew had already begun his political career as a well-known member of junior king Béla's court, therefore it was not necessary to distinguish him from the other lords by specifying the name of his father. Matthew I married Margaret from an unidentified family. The marriage produced five children (four sons and a daughter): the eldest one was Mark I, ispán (comes) of Hont County in 1247, but there is no further information about him; Stephen I, master of the stewards from 1275 to 1276 and from 1276 to 1279; Matthew II, a notable general and palatine of Hungary (1278–1280; 1282–1283); and Peter I, who also held powerful positions, including palatine (1275–1276; 1277; 1278; 1281) and who, furthermore, was the father of the notorious Matthew III.

They had also a daughter, who married to the Moravian noble Zdislav Sternberg, a loyal bannerman of the Csák clan. Their son, Stephen Sternberg (or "the Bohemian") later inherited the Csák dominion because of the absence of a direct adult male descendant after the death of Matthew III in 1321. After Matthew I's death, his wife, Margaret joined the Dominican monastery at the 'Rabbits' Island and lived there until her death. During the first years of Béla IV, a new aristocracy arose, whom the king could rely on. Béla's main purpose was to restore the royal power that had weakened during his father's rule; e.g., he ordered the burning of his advisors' seats, because he wanted to force them to stand in the presence of the king. As he also wanted to strengthen the position of the towns, he confirmed the charter of Székesfehérvár and granted new privileges to several key towns in the kingdom. Furthermore, Béla dismissed his father's former loyal followers and advisors (during this time, for example, former palatines Denis, son of Ampud was blinded and Julius Kán was imprisoned). That consideration explains Matthew's rise in a short time from obscurity to the largest positions.

Following the disastrous Battle of Mohi (11 April 1241), Béla IV fled the scene to Spalato (today: Split, Croatia), where Matthew I was also a member of the king's men. After the Mongol invasion of Hungary, Matthew I was appointed master of the treasury, thus he became responsible for the royal's economic and financial affairs. Beside that position, he was also ispán of Sopron (1242) and Pozsony Counties (1242–1245).

Béla IV donated Chrenóc (; today part of Chrenovec-Brusno) in Nyitra County to Matthew I in 1243. One year later he acquired the estate of Pruszka (today: Pruské, Slovakia) in Trencsén County, which previous landowner died without heirs. Later Matthew I exchanged that land to Tunig, Pozsony County. According to a royal charter issued in 1249, Béla IV formerly also donated Racsic (; today part of Nitrica) to Matthew, who was already dead by that time. There is no source about his inherited possessions, thus data on his four sons' inherited estates also does not exist. Consequently, he did not initiate his family through the establishment of oligarchical power with land acquisitions, he just marked its direction (from the ancient estates of the genus in Fejér County to northwest).

Matthew I Csák was last mentioned by sources on 12 December 1245. As it's written above, he had already died by 1249, according to the king's diploma. In contrast his widow, Margaret, who lived in the 'Rabbits' Island for a long time, claimed in 1276 that she was 51 years old and her husband died 22 years ago, so in 1254. The royal charter, however, is a more reliable source, because medieval people found the years and times difficult to keep track.
