Haji Bayram Veli

Haji Bayram Veli (1352–1430), born Numan in Ankara, was an Ottoman Sufi poet and saint who founded the Bayramiyya dervish order. He made the pilgrimage to Mecca with his master, who continued to teach him on the journey.

Inheriting his master's authority in 1412, he returned to Ankara, where his preaching and hymns drew crowds. When the order's growth alarmed the authorities, he was sent to Murad II in Edirne, where the sultan let him lecture at court.

A later legend credits Bayram with foretelling Mehmed II's conquest of Constantinople. He died in Ankara in 1430, leaving the order to his disciple Akshamsaddin.
