Záh (gens)

Záh (Zaah or Zách) was the name of a gens (Latin for "clan"; nemzetség in Hungarian) in the Kingdom of Hungary. The clan was one of the 108 gentes during the Hungarian conquest of the Carpathian Basin and located in Nógrád County along with the Kacsics, Kartal, Kökényesradnót and Tomaj clans.

The name is of an unknown ancient origin or seems to be of local, post 895, origin being a shortform abbreviation from the Slavic description Zahora (meaning: behind the mountains), which perfecty describes the families' crest, the Nógrád County, as seen from the west, the north and the east where, just across the hills, most Slavs lived since the 5th century.

The gens provided several high dignitaries in the era of Árpáds, including Nicholas, son of Borsa who served as ispán (Count; comes) of Sopron County between 1221 and 1233. Conrad, son of Albős (c. 1240–1269) was ispán of Győr County and chief cellarer for the Queen. Job functioned as bishop of Pécs from 1252 until c. 1282 and ispán of Moson County since 1272. He was the uncle of Felician Záh.
