Nogai Khan
Michael VIII, the Byzantine Emperor based in Constantinople, attempted to stay on friendly relations with both khanates. Hulagu had been negotiating for a lady of the imperial family of Constantinople to be added to his number of wives, and Michael selected his illegitimate daughter Maria. He also betrothed another of his daughters, Maria's sister Euphrosyne Palaiologina, to Nogai Khan, head of the Golden Horde. Both khanates maintained an attitude of tolerance towards the Christians.
