Benedict, Palatine of Hungary

It is possible that Benedict originated from the gens (clan) Osl. He had a namesake son, who functioned as vice-judge royal in 1221.[1]

Due to the lack of sources and the presence of multiple barons named Benedict in the period simultaneously, there are a number of difficulties in drawing and defining his career path. Based on chronology and political situation, Benedict was a faithful partisan of King Emeric, who had to face series of rebellions from his younger brother, Duke Andrew, throughout his whole reign. According to historian Attila Zsoldos, he is definitely not identical with Benedict, son of Korlát or that another namesake noble, who held ispánates after 1205, when Andrew II ascended the Hungarian throne.[2]

Benedict started his career as ispán of Nyitra County in 1198.[3] After Emeric routed Andrew's army near Lake Balaton in the summer of 1199, forcing the duke to fled Austria, the king, replacing Nicholas, installed Benedict as Ban of Slavonia,[4] taking over the administration of the provinces Croatia and Slavonia, which then belonged to Andrew's duchy.[2][5] Simultaneously with the dignity of ban, Benedict served as ispán of Zala County too, which then attached to the Duchy of Slavonia.[6] As ban, Benedict donated his estate Vaška in Virovitica County to the Knights Templar.[1] Benedict held both positions until 1200, when Emeric reconciled with his younger brother, and Andrew was allowed to return to his duchy.[4]

Thereafter, Benedict administered Bács County in 1201. According to a non-authentic charter, he held the office still in 1202.[7] Benedict was made Palatine of Hungary in 1202, holding the dignity until 1204, Emeric's death.[8] Beside that, he was also referred to as ispán of Bihar County between 1202 and 1203.[9] Benedict is the first office-holder, who was styled as simply "palatinus" without the prefix or suffix "comes" ("count").[10] He was also one of the last palatines without any known preserved charters issued by him.[11]

Following the death of Emeric in 1204, Benedict plausibly belonged to the partisans of the child king Ladislaus III and his mother Queen Constance of Aragon, opposing Andrew's regency. Therefore, when Andrew II ascended the throne in 1205, Benedict lost all political influence and never gained any offices.[12] According to Slovak historian Angelika Herucová, Andrew II had problems getting rid of previously powerful noblemen, so it cannot be ruled out that Benedict continued his career as ispán of several counties – Bodrog (1205), Sopron (1206–1208), Újvár (1209), then Ung (1214) counties – nor he is identical with that infamous Benedict "the Antichrist", who governed Halych with brutal means on behalf of the Hungarian king from 1210 to 1211.[13]
