Nogai Khan

Nogai, or Noğay (Kypchak and Turki: نوغای; also spelled Nogay, Nogaj, Nohai, Nokhai, Noqai, Ngoche, Noche, Kara Nokhai, and Isa Nogai; died 1299/1300) was a general and kingmaker of the Golden Horde. His great grandfather was Jochi, son of Genghis Khan.

Though he never formally ruled the Golden Horde himself, he was effectively the co-ruler of the state alongside whatever khan was in power at the time and had unrestricted control over the portions west of the Dnieper. At his height, Nogai was one of the most powerful men in Europe and widely thought of as the Horde's true head. The Russian chroniclers gave him the title of tsar, and the Franciscan missionaries in the Crimea spoke of him as a co-emperor. Nogai was also a notable convert to Islam.
