Hanukkah Khagan was a Khazar Khagan who reigned during the mid to late ninth century CE. Hanukkah was the brother of Obadiah and succeeded his great-nephew Manasseh I to the throne. No contemporary records from his reign survive; however, he is known from the Khazar Correspondence between Hisdai ibn Shaprut and the Khazar king Joseph. Historical authenticity and accuracy of the only document mentioning his name has been questioned.[1]
Hanukkah was succeeded by his son Isaac.
