the command of the Keraites, and Gurkhan fled. Relationship with Temujin Toghrul was, like Jamukha, blood-brother of Temujin. He led the coalition against Merkits when Temujin's wife Börte was abducted in 1183, joined by his brother Jakha Gambhu, Jamukha and Temujin. Two of the tribal chiefs, Dair Usun and Toqto'a fled the camp, probably informed by people who had seen the army move. The coalition easily won the fight that followed and about 300 Merkit perished. The chiefs distributed the booty among themselves and gave the Merkit wives to the warriors. The children became slaves. Börte was found later in the evening. Toghrul returned to the Kerait camp with his men, proud of an easy victory.

The men were slaughtered, the women were taken as concubines and the children were adopted or became servants and slaves. Some thousands of Tatar who had resisted and then escaped entrenched themselves. This was the time when he was given the name Wang Khan (). Later that year he was overthrown by Erke Qara, whom he had not been able to assassinate and returned with the Naiman army. Many Keraites who were dissatisfied with the command of Toghrul probably also helped to drive Toghrul out. He fled to Yelü Zhilugu without even going to seek the help of Temujin. He stayed there a year according to the Secret History. It was after leaving the Qara-Khitai that he finally decided to join Genghis Khan. According to Rashid al-Din, he would have
