Despite his impressive title, Genghis was but one of several khans, or chieftains, and in the years that followed, tensions between him and other leaders—particularly Ja-mukha—would grow. In 1198, both men aided the Chinese in a successful war against a common enemy, the Tatars. The shared effort, however, did little to reunite Genghis and Ja-mukha, and in 1191, clans opposed to Genghis's leadership recognized Jamukha as Gur Khan, or "sole ruler." They then launched an attack against Genghis, who managed to ward them off with the aid of Toghrul's troops.
In 1203, however, Jamukha influenced Toghrul to join his side, and they plotted to double-cross Genghis. Once again, the celebration of a betrothal—that is, the promise of a marriage, in this case of Toghrul's son to Genghis's daugh-
King. He also formed a strong alliance with the Catholic Church, and instituted a system of church schools to strengthen education throughout the country.

In later years, Brian referred to himself as "emperor of the Irish," and seems to have consciously modeled his rule on that of Charlemagne (see entry) and other great European figures. Though he had authority over the other kings of Ireland, many opposed his power. Eventually his enemies formed an alliance with the Danes, and marched against Brian on Good Friday, April 23, 1014. Brian was killed, and though ironically his side won the battle, their cause was lost without their leader. Brian's vision of Irish unity died with him.
Ter—would provide the occasion for the betrayal. Toghrul's son tried to lure Genghis to a feast, where they would kill him, but one of Genghis's advisors figured out what was going on, and urged him not to go.
Genghis gathered his forces, and called on the clans that had sworn their allegiance to him, but they doubted his ability to win against the superior forces of his enemies, so they chose to stay out of the battle. That battle was inconclusive, but soon afterward, Genghis defeated Toghrul. Next came Jamukha, who he captured some months later. Reportedly Genghis offered his old friend the opportunity to let bygones be bygones, but Jamukha was supposedly so ashamed at his capture that he demanded to be killed. Whether or not this is true, Genghis's men killed him, and in 1206 the Mongols united as a nation for the first time and proclaimed Genghis "ruler of all men."
