Each one of these Khanates claimed to be the legitimate successor to the Golden Horde. The Great Horde itself was centered on the Golden Horde's national center of Sarai, with its territory being led by four tribes - the Qiyat, the Manghud, the Sicivud, and the Qonqirat.[5] The Great Horde was originally simply referred to as the Orda, or Horde, but it became increasingly important for the disparate hordes in the region to be distinguished from each other, which led to the first mention of the "Great Horde" in sources in the 1430s. The name "Great Horde" might have been used to directly link the now greatly reduced administrative center of the Horde to the original greatness of the Golden Horde.[6]: 13–14
