Abd al-Razzaq ibn Fazlallah
Abd al-Razzaq ibn Fazlallah was a landowner of Bashtin near Sabzavar in Khurasan who founded the Sarbadar state. Oppressed by the taxes of Ala al-Din Muhammad, governor under Togha Temur, he killed an official in 1337 and revolted.
His followers defeated government forces and seized Sabzavar in 1337. He ruled with the title of amir and struck coins in his own name, but in 1338 he was stabbed to death by his brother Wajih al-Din Masud, who succeeded him.
