Ka'us III

During his reign, relations with the Kia'id Khan Ahmad Khan flourished, and by 1514 family ties were between the Paduspanids and Kia'ids. Nine years later, Ka'us, along with the Marashiyan ruler visited the court of the Safavid king Ismail I. Not much more is known about Ka'us; he died after being poisoned by his son Kayumarth III, whom Ka'us had imprisoned for unknown reasons.
