Dukes · Samarkand: the Western Qarakhanids · as at first light, 1 January 1200

Bilge Khan of Otrar

Otrar (Farab), on the Syr Darya where the Arys joins it, is the chief town of the middle river and the gate between the oases and the Qipchaq steppe.

Its ruler in the 1200s is Taj al-Din Bilge Khan, a Qarakhanid, cousin of Uthman of Samarkand and vassal of the gurkhan; he fights for the gurkhan at Andkhud in 1204, goes over to Muhammad of Khwarazm about 1210, and is exiled to Nasa and killed. Whether he already holds Otrar on 1 January 1200 is not pinned; no other lord of Otrar is named for these years.

What the year holds

What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.

  1. 1204Fights at Andkhud with Tayangu and Uthman against Mu'izz al-Din.Depends on: The Ghurid attack on Khwarazm. Stopped by: Peace between Ghurids and Khwarazm.
  2. about 1210Submits to Muhammad of Khwarazm; later exiled to Nasa and executed.Depends on: Muhammad's war with the gurkhan. Stopped by: Far beyond 1200.

Where the sources disagree

Evidence: Named only from 1204 onward; his tenure in 1200 is an inference.

On the map: The oasis is traced roughly; its limits towards Yasi and Sawran are not known.
