The oldest extant book on the genealogy of the Safavid family is Safvat as-safa and was written by Ibn Bazzaz in 1350, a disciple of Sheikh Sadr-al-Din Safavi, the son of Sheikh Safi ad-din Ardabili.
According to Ibn Bazzaz, the Sheikh was a descendant of a Kurdish man named Firooz Shah Zarrin Kolah who was from Sanjar, southeast of Diyarbakir.
Later Safavid Kings themselves claimed to be Seyyeds,[1] family descendants of the Islamic prophet Muhammad.
The great-grandson of Sheyk Safi, Sheik Joneyd, got married with Khadijeh Khanoum sister of Uzun Hassan and daughter of Ali Beg by his wife Theodora of Trebizond, daughter of Alexios IV of Trebizond.
Heydar, son of Joneyd, married Katherina who was a daughter of Uzun Hassan by his wife Theodora, daughter of a Bagrationi Georgian princess and John IV of Trebizond.
