Left Wing princes

According to Rashid-al-Din Hamadani (1247–1318), Genghis Khan's eldest son, Jochi, had 14 sons. When he died, they inherited their father's dominions as fiefs under the rule of their brothers, Batu Khan, as supreme khan and Orda Khan, who, although the elder of the two, agreed that Batu enjoyed primacy as the Khan of the Golden Horde (Jochid Ulus). Orda, along with some of his younger brothers, ruled the eastern wing of the Golden Horde while Batu and others ruled the western wing of it. These Hordes are known as the "White", "Blue" and "Grey" (Shaybanid) Hordes in Slavic and Persian historiography. The two main divisions are also known as Batu's Ulus (district) and Orda's Ulus.

According to the Tarikh-i Dost Sultan written by Ötemish Hajji in Khiva in the 1550s, Batu's ulus was officially known as the "White Horde", Orda's the "Blue Horde" and Shiban's the "Grey Horde".

The terms White and Blue Horde have been much misused causing enormous confusion due to modern sources. History books by notable authors left the name of Orda's son and successor, Qun Quran, and others quickly followed it.

In Russian chronicles, the Blue Horde is described as the eastern part of the Golden Horde, which was being found in the allegiance on west, and which was being governed by the descendants of Orda Khan. After the succession struggle of Batu's line in the 1360s, known as "great troubles", the authority both parts of the Golden Horde passed to the eastern Jochids.

According to the Russian chronicles Blue Horde was located to the east of the Volga and is mentioned twice: the first time in connection with the great troubles, which was completed by the accession of Tokhtamysh ("tsar from blue horde"), and the second - with the invasion of Timur in 1395.
