Nogai Horde
In the 14th century, Edigu, a Tatar from the Manghud tribe and one of Tamerlane's greatest strategists, settled on the north shores of the Black Sea, establishing the Nogai Horde and laying the foundations for the Crimean Khanate. Edigu's death was followed by infighting between his descendants, until, in the 15th century, Yusuf became the khan of the Nogai Horde.
