House of Ispahbudhan
The House of Ispahbudhan or the House of Aspahbadh was one of the seven Parthian clans of the Sasanian Empire. Like the Sasanians, they claimed descent from the Achaemenid dynasty. They also claimed descent from the legendary Kayanid figure Isfandiyar, who was the son of Vishtaspa, who according to Zoroastrian sources was one of Zoroaster's early followers.
