Aaron I
Aaron ben Nisi was a Jewish ruler of the Khazars mentioned in the Khazar Correspondence. He reigned around the year 900 CE. He was the son of Nisi ben Menasseh. Little is known about his reign. As with other Bulanid rulers, it is unclear whether Aaron was Khagan or Khagan Bek of the Khazars, although the latter is more likely.
He was succeeded by either Menahem or Benjamin.
