Taj al-Dawla Ziyar

Taj al-Dawla Ziyar was the Baduspanid ustandar of Rustamdar and Ruyan from 1325 until his death, and the first of his line to take the title Malik. In 1325 he seized the throne after instigating his son Iskandar to murder his brother Nasir al-Din Shahriyar.

When another brother, Izz al-Dawla, challenged him with the Ilkhan's support, Ziyar defeated him and consolidated his rule over Ruyan. He died at Kavir in 1333, leaving sons including Jalal al-Dawla Iskandar and Fakhr al-Dawla Shah-Ghazi.
