Seven Parthian clans
Only two of the seven - the House of Suren and the House of Karen - are actually attested in sources date-able to the Parthian period. The placement of the remaining five in Parthian times is "in all probability not in accordance with reality." "It may be that [...] members of them made up their own genealogies in order to emphasize the antiquity of their families."
The seven houses with their respective main fiefs and ruling-family seats were:
- the House of Ispahbudhan, of Gurgan
- the House of Waraz, of Eastern Khorasan
- the House of Karen, of Nahavand
- the House of Mihran, of Ray
- the House of Spandiyadh, of Comisene (Semnan)
- the House of Zik, of Atropatene
- the House of Suren, of Sakestan (Sistan)
