Jochi Qasar

Jochi Qasar (1164–c. 1219), second son of Yesugei and brother of Genghis Khan, earned his nickname Khasar, after a fierce hunting dog, for bravery and archery. With Temüjin he killed half-brother Begter over hunting spoils. In 1203, after the defeat at Khalakhaljid Sands, a false surrender in his name lured the Kereite Ong Khan to ruin.

He commanded the centre against Naiman Tayang Khan and in 1206 received four thousand households on the Hulunbuir steppe. In 1213 he led the left wing against the Jin, taking Jizhou and other cities. His descendants became the Khorchin Mongols.
