Hanukkah ben Obadiah

Hanukkah, or Chanina, was a hypothetical Khazar ruler who supposedly reigned during the mid to late ninth century CE. Hanukkah/Chanina was said to be the brother of King Obadiah and to have 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. Constantin Zuckerman pointed out that the names of Hanukkah and Obadiah do not appear in the list of Khazar kings in Judah ben Barzillai's Sefer ha-Ittim. Scholars believe their omissions raise questions as to whether they really existed.
Hanukkah was succeeded by his son Isaac.
