Hagiography is the literary genre of biographies about holy people. In Islamic Persia, hagiography developed as a genre during the eleventh century CE, in Khurāsān, a region from which many eastern Ṣūfīs came. It tended to focus on Sūfī saints. The tradition declined around the sixteenth to eighteenth centuries CE, but was revived in the nineteenth and still exists today online.[1]
