Qayaliq (Kayalyk, near the village of Koylyk in Sarkand district, Kazakhstan) is the old capital of the Qarluq jabgu, an almost independent Qarluq possession inside the Karakhanid state in the 11th and 12th centuries.
Excavation shows a town of about one by one-and-a-fifth kilometres with a cathedral mosque, brick mausolea of the late 12th and early 13th century with Muslim burials, a local mint of silver and copper, rich houses with underground heating, a Buddhist temple and a Manichaean temple (12th to 13th century). It is a Muslim Turkic capital with Buddhist and other temples beside the mosque. The khan keeps his people, title and faith and sends tribute: the model of Qara Khitai rule.
Who he is
- Name
- Arslan Khan is the Qarluq ruler of Qayaliq in 1211 and 1218; whether he held it on 1 January 1200 is not pinned

Wikipedia (Mongol conquest of the Qara Khitai) names Arslan Khan as ruler of the Qarluq city Qayaliq and a son-in-law of Chinggis, who may have joined Jebe in 1218. The excavation summary names no ruler. No Qarluq ruler is named for 1200 in anything we could open.

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.

Places of note

Where the sources disagree
- The campaign board entry qayaliq: coordinates 45.15 N 78.72 E, 'Buddhist and Nestorian communities'. The excavation summary has Buddhist and Manichaean temples; Rubruck (1253) believed a man with an inked cross was a Christian. No church is excavated. The coordinate is plausible (Koylyk is in Sarkand district) but the summary gives none.
Evidence: Archaeology (the excavation summary) is the best evidence on this ground; the ruler is not named for 1200.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
