Orda's Ulus or more appropriately, the Left wing of the Jochid Ulus was one of the uluses within the Mongol Empire formed around 1225, after the death of Jochi when his son, Orda-Ichen (Орд эзэн, Lord Orda), inherited his father's appanage by the Jaxartes.
Throughout its history rule over the Khanate was often contested between members of the Shaybanid and Taibugid dynasties; both of these competing tribes were direct patrilineal descendants of Genghis Khan through his eldest son Jochi and his fifth son Shayban (Shiban).
As recorded by Rashid-al-Din in his Jami al-Tawarikh, 4 September 1236 was the date on which the sons of Jochi - Batu, Orda, and Berke, Ugedei’s son Kadan, Chagatai’s grandson Büri, and Jenghiz Khan’s son Kulkan declared war on the Mokshas, Burtas and Erzyas.
In the 13th century, the leader of the Golden Horde, Nogai Khan a direct descendant of Genghis Khan through Jochi, formed an army of the Manghits joined by numerous Turkic tribes.
Orda Ichen was the first-born son of Jochi, his younger brothers were Batu, Berke, Shayban, Sinkur, Toga-Timur and Baul-Teval.
