Kuchlug, son of Tayang

Kuchlug is Tayang's son and, after 1204, the last real leader of the Naiman.

In 1200 no source shows him doing anything. In 1204 he mocks his father's caution and urges a charge; after the defeat he flees west (Wikipedia: towards the Black Irtysh), in 1205 joins Toqto'a of the Merkit at Buqdurma (the Bukhtarma) and, after Toqto'a's fall, goes through the Uyghur and Qarluq lands to the Gur Khan on the Chu (Secret History 198); he marries the gurkhan's daughter and seizes the Qara Khitai throne in 1211 (1212 or 1213 in Li Tang's summary) and rules until his death in 1218. He was born a Christian of the Church of the East; Juvaini says his wife persuaded him to turn Buddhist.

What the year holds

Where the sources disagree

  • Wikipedia's Kuchlug article says he fled 'toward the Kara Irtysh' in 1204; the Secret History (198) sends him to join Toqto'a at Buqdurma and then through Uyghur and Qarluq country to the Gur Qan.

Evidence: Nothing is dated to the 1190s; the facts are from 1204 and later.

On the map: No map part.
