Genghis Khan, a Mongolian warrior-ruler who consolidated nomadic tribes into a unified Mongolia and whose troops fought from China's Pacific coast to Europe's Adriatic Sea, creating the basis for one of the greatest continental empires of all time. The leader of a destitute clan, Temüjin fought various rival clans and formed a Mongol confederacy, which in 1206 acknowledged him as Genghis Khan (“Universal Ruler”).

For the tribe and for Jamuqa it was a decisive moment.

Men who were sworn brothers share one life. But I began to question whether Jamuqa was truly my blood-brother for all eternity.

It was not right that our differences should force a feud but my wife stopped me from going after him. She warned that one day my blood-brother would ride against me.

For Temujin this feud brought back the darkest memory of his childhood.

I knew where a war between brothers would lead, even when we were starving my brother Belgutei had betrayed us, he refused to share the spoils of a hunt. He died of his wounds.
