Kayqubad I
The order originated in Sohrevard in today's Iran though it spread all over the Islamic world under its founder's nephew, Abu Hafs Umar al-Suhrawardi (1145 – 1234 CE), who was sent by the Caliph in Baghdad as an ambassador to the Ayyubid Sultan Al-Adil I of Egypt, to Khwarezm-Shah Muhammad of Bukhara and to Kayqubad I, Sultan of Rûm.
