Hont-Pázmány (Hunt-Poznan) was the name of a gens ("clan") in the Kingdom of Hungary. The ázmáGesta Hunnorum et Hungarorum mentions that the ancestors of the family, the brothers Hont (Hunt) and Pázmány (Pazman), originally from the Duchy of Swabia in the Holy Roman Empire, arrived in the late 10th century to the court of Grand Prince Géza of the Magyars:
The next arrivals were Hunt and Pazman, two half-brothers, courageous knights of Swabian origin. These two and their retainers had been journeying through Hungary with the intention of passing over the sea when they were detained by Duke Géza, and finally they girded King Stephen with the sword of knighthood at the river Hron, after the German custom.
The clan Hontpaznan was mentioned for the first time in 1226 in a charter. Several prominent families of the kingdom (e.g., Szentgyörgyi and Forgách) descended from the gens.
The branches of the clan
By the 13th century, the clan divided into 12 branches: the branch of Bozók held possessions in Hont County and they had two castles; the possessions of the branch of Födémes (now Ipeľské Úľany) were located in Hont and Borsod counties and their castle in Borsod County was built without royal authorization and therefore, it was demolished in 1298; the members of the branch of Bény owned lands in Hont and Nyitra counties and they held three castles; the branch of Csalomja (today Malá Čalomija) held possessions in Hont county; the lands of the members of the branch of Gímes (now Jelenec) were located in Nitra County and they had a castle built there; the branch of Szeg possessed lands in Nitra County; the members of the branch of Szentgyörgy and Cseklész (today Bernolákovo) held possessions in Prešporok County and they had three castles by the end of the 13th century; the possessions of the branch Pogány of Garadna were located in Trencsén county; the members of the branch of Újhely owned lands in Bihar County where they had a castle built; the branch Pázmány of Panasz held possessions in Bihar County; the members of the branch of Beszterce owned lands in Bihar County; the possessions of the branch of Czibak-Batthyányi were also located in Bihar County.
Notable members of the clan
The first notable members of the clan were the brothers Hont and Pázmány who assisted Géza's son, the future King Stephen I of Hungary against his relative, the pagan Koppány who claimed for Géza's inheritance. The deed of foundation of the Pannonhalma Archabbey (issued in 1001) referred to both brothers as the king's military leaders (duces). The brothers were granted possessions on the north-western parts of the kingdom (primarily in present-day Slovakia). Hont County was named after one of them.
Lampert (?–1132) founded the Abbey of Bozók. His first wife was the sister of King Ladislaus I of Hungary. He held about 30 possessions and thus he was one of the wealthiest landowners of the kingdom. In 1124, he took part in the campaign of King Stephen II of Hungary against Dalmatia. Lampert was murdered by the followers of King Béla II the Blind, because he was suspected of supporting Boris Kalamanos's claim to the throne.
Around 1201, Martin (?–1236/1245) held the office of count (comes) at the court of the future King Andrew II of Hungary, and served as the Ban of Croatia and Dalmatia. In 1202 and between 1212-1213, Martin was the Ban of Slavonia and he was styled Ban also in 1224 and 1234. In 1214, he held the office of judge royal (országbíró). He founded the Abbey of Ipolyság (today Šahy in Slovakia).
Achilles (b. 1210–1252) was bishop of Pécs between 1251 and 1252.
Lampert (of the branch of Csalomja) was bishop of Eger from 1247 to 1275.
Ivánka II from the Szeg branch was Judge royal sometime before 1289.
Gímes branch
Andrew I was a confidant of Béla IV of Hungary. He erected the castles of Gímes (Jelenec) and Turóc (Zniev). His sons were John, archbishop of Kalocsa from 1278 to 1301, and Thomas III, an influential baron. Both were strong partisans of King Andrew III of Hungary. Another sons were Andrew II and Ivánka III, who were killed by Matthew III Csák.
