Achilles from the kindred Hont-Pázmány

Achilles from the kindred Hont-Pázmány (Hungarian: Hont-Pázmány nembeli Achilles pécsi püspök) was a prelate in the Kingdom of Hungary in the middle of the 13th century. He was provost of the collegiate chapter of Székesfehérvár and vice-chancellor between 1243 and 1251, and bishop of Pécs from 1251 until his death in 1252.

Achilles was one of the five children of Pázmány from the kindred Hont-Pázmány. Although the genus Hont-Pázmány was one of the most illustrious clans in the Kingdom of Hungary, its Újhely branch from which Achilles descended was less prosperous. The small family lands were located in the region of the rivers Berettyó and Körös.

All the same, Achilles was admitted to the royal court sometime after 1225 where he was employed as royal chaplain. His early carrier is uncertain, because there were four namesake prelates in the Kingdom of Hungary in the 1230s and 1240s. He can most probably be identified with one Achilles, provost of the cathedral chapter of Esztergom from around 1236. When the Mongols invaded the Kingdom of Hungary in 1241, this Achilles fled to Dalmatia similarly to King Béla IV of Hungary. Since Archbishop Matthew of Esztergom was killed by the Mongols in the Battle of Mohi, Achilles administered the archdiocese for more than two years.

Following the withdrawal of the Mongols Provost Achilles was at least twice appointed by the pope to investigate the circumstances of appointments to higher Church offices. Achilles himself was transferred to the collegiate chapter of Székesfehérvár in September 1243. Head of the prestigious chapter, Achilles also became the vice-chancellor, the leader of the royal administration. The royal chancery started to function more uniformly under his auspices, and the registration of the charters issued by the chancery was also begun in this period. King Béla IV of Hungary granted him a landed property in Ugocsa County which suggests that the monarch also respected Achilles's work.
