Two years later, in 1221, the Mongol conquest pushed the Turko-Iranian Oghuz tribes including the Choudur from the Syr Dara region into the Kara Kum area and along the Caspian Sea.
•
Many Choudur appear to have stayed on the Mangyshlak Peninsula from then through the Timurid and the Shaybanid Uzbek periods, beginning the Turco-Mongol transformation of these originally Turko-Iranian people.
•
The Kalmuks moved into the Mangyshlak Peninsula, the Sayin Khan confederation broke up and the Choudur ended up southeast of Khiva loosely confederated, but under the authority of the Yomud.
•
Most of them were members of the Imir, Dukur, Düker (Döger), Igdir, Chavuldur, Karkin, Salor or Agar (Ajar) tribes.
