Atyusz (also Oghuz or Ochuz) was the name of a gens (Latin for "clan"; nemzetség in Hungarian) in the Kingdom of Hungary, several prominent secular dignitaries came from this kindred.
Beside that the phrase "de genere Almad" ("from the kindred Almád") also appears in charters issued in 1274 and 1276, the late members of the genus, Bánd III and Csaba were styled this.
[1] The earliest known member of the family was Bánd I, who died in 1117 according to the establishing charter of the Almád Abbey, but before that, forced to swear his two sons, Atyusz I and Miska I to found the monastery.
The second and surviving wife of Bánd I was a certain Gyönyörű, who was not the mother of the two sons, and who went on a pilgrimage to Jerusalem following his husband's death (Atyusz I referred to her as his "stepmother").
[3] In 1121, Atyusz I founded the Benedictine monastery of Almád Abbey, dedicated to Mary the Virgin and the All Saints, and also donated eight villages.
In 1221, Béla III of Hungary confiscated Atyusz the Great's land of Kamešnica in Croatia and donated to the Diocese of Zagreb.
[7] In 1232, he was involved in a disagreement and litigation regarding the ownership of some lands against Bartholomew, Bishop of Veszprém, which escalated into the famous Kehida Diploma, an important document for the formation of royal servants' self-government.
Their son Atyusz V was charged disloyalty by Ladislaus IV of Hungary, who confiscated his ownership, the Szentmiklós Castle and donated to Benedict III, Archbishop of Esztergom and his brothers, Dedalus, ispán of Zala County (1273–1274), Beke and Stephen.
[20] János Karácsonyi, in his namesake work (1900–1901), first discovered the separate genus of Atyusz and also systematized the family's three branches.
[21] In 1924, palaeographer Emil Jakubovich published the last testament of Stephen, son of Miska I, while Imre Szentpétery founded and translated the deed of the foundation of the Almád Abbey in 1927.
