The Kar-Kiya dynasty, also known as the Kiya'ids, was a local Zaydi dynasty which mainly ruled over Biya-pish (eastern Gilan) from the 1370s to 1592.

[1] The Kar-Kiya dynasty helped Shah Ismail I to establish Safavid Iran and later became one of its vassal states.

The Safavid shah, Abbas I put an end to the Kar-Kiya dynasty and the neighbouring Eshaqvand Dynasty by dispatching an army to Gilan in 1592.

The site also entombs one of their ancestors, Sayyed Kar-Kiya, who was killed in 1243 or 1244.
