Thomas was born into the gens Baksa, as the son of Simon I, the ispán of the royal forest of Patak in 1262. He had five brothers, including the illustrious military leaderGeorge, and a sister. Thomas had two sons from his unidentified wife, Ladislaus, who inherited his wealth and was ancestor of the Sztritei family, and Doncs.
Career
The Baksa clan, which had originated from the valley between the riversBodrog and Tisza, possessed villages and landholdings in Northeast Hungary, mainly Zemplén County. According to contemporary sources, Thomas owned Tiszalúc and Tarcal. The Baksa clan supported Duke Stephen in the conflict with his father, King Béla IV of Hungary, as their lands laid in the territory of the rex junior after the division of the kingdom in the early 1260s. When the civil war between Béla and Stephen broke out in 1264, the royal army forced Stephen to retreat to Feketehalom. Thomas and his brothers followed their lord and have found shelter in the fort. They were among those partisans, who relieved the castle, when Béla's army unsuccessfully besieged it. Following Stephen's ascension to the Hungarian throne, Thomas was styled as Count of the Coursers in 1271, which was considered a minor court position and he is the only known office-holder. For his loyal service, he was granted the estate of Kengyeltelek, near Bodrogszerdahely in that year. After the death of Stephen V, he remained a supporter of the royal power during the rule of the child Ladislaus IV of Hungary, who donated the village of Radvány to Thomas in 1280. In the subsequent years, Thomas and his younger brothers acquired several lands along the upper course of the river Tisza. He bought Semjén and Kövesd in the territory of Bodrogköz and Halász in Szabolcs County in 1280, Sztrite in 1281. The Baksa brothers, including Thomas, fought in the battle of Lake Hód, near Hódmezővásárhely, against the Cumans in 1282. He bought a portion of Karcsa from the Hospitaller Order of Saint John in that year. Thomas and his brother, Baksa bought Eszeny from the gens Becsegergely in 1283. Thomas was granted the right of patronage over the provostry of Lelesz by King Ladislaus IV in 1283. The king also handed over the estate of Rát to Thomas and his brothers upon their request in that year. Thomas was granted Ásvány as a compensation by Andrew Bacskai in 1286. It is plausible that Thomas and some of his brothers joined the rebellion against Ladislaus IV. After the battle along the river Zsitva in March 1287, Ladislaus confiscated their lands, including Thomas' right of patronage over Lelesz. After the promulgation of the mass amnesty around November, Thomas and his brothers regained their lands and the patronage over Lelesz in February 1288, through the possible mediation of their royalist brother, George Baksa. Thomas died sometime after 1288.
