Khvajeh Ali Safavi
Khvajeh Ali Safavi, also called Khvajeh Ali Siyahpush (c. 1370–1427), was the third head of the Safavid Sufi order at Ardabil, succeeding his father around 1391. Grandson of founder Safi al-Din Ardabili, he led it through the age of Timur.
Tradition credits him with saving Tatar tribes of Sham from Timur's vengeance; they became followers later known as the Qizilbash. Under him the order turned decisively to popular Shi'ism. He died in 1427 and was succeeded by his son Ibrahim Shah.
