Ayyub Khan (Kipchak leader)

Aepa Khan (Persian: ايوب خان, Tatar: Äyyüb, Russian: Аепа (Ayepa)) (died 1117) was a ruler of the Kipchak commonwealth. He was a grandfather of Andrew the Pious. There is some information about his war against Vladimir Monomach. Later, Kipchakia, still ruled by Ayepa, also attacked Volga Bulgaria in union with the Kievan Rus.

Etymology
Aepa may be a slavicization of the Arab name Ayyub. A recent and more accepted theory reconstructs it to Ayoba or Ayapa (moon-father).
