"The pleasure and joy of man lies in treading down the rebel and conquering the enemy, in tearing him up by the root, in taking from him all that he has." -- Genghis Khan
It was not long after Temujin's revenge that he once again picked up the sword and ordered his horsemen to war. With promises of glory, wealth and new plunder, the great Khan rode westward with over 21,000 men. In early october, Genghis Khan and his army crossed the Selenga river proclaiming loudly "if this river can not check our advance, why should we not continue to grow". Even with winter closely approaching, Genghis Khan began his newest war against the forest tribes of the Oirats. Having lost an earlier war to the Kyrgiz, the Oirats found themselves eager to embrace this new Great Khan, and while those loyal to the Kyrgiz fought against the Genghis Khan and his warriors, they were defeated and subdued before the first fall of snow. Feeling both sympathy and a sort of Kinship with the Oirats, Temujin made them unto brothers and offered to them the glory that would fall on 'all the peoples of the felt tent.' Genghis Khan settled in for the winter, but it is said that he was visited by the war gods and given many visions. One snow drunk winter night, he said he saw for himself a great crown of gold and many jewels, that encircled the whole of the earth. His conquest's had only just begun.
With the mongol lands unified by Temujin, his attentions soon turned further westward towards the powerful Naiman and the declining Kyrgiz. For it was clear that they would have to also accept him as their King. Barely waiting for the winter to pass, Genghis Khan declared war against the two tribes of the Naiman on the 1st of February, 1183 A.D. according to the historical reckoning. Riding with nearly thirty five thousand warriors, the mongols swept into the Sain, overpowering all resistance. With the region of Sain thoroughly in the mongol's hands, Genghis Khan decided to fell two birds with one stone and made it clear he intended to war with the Kyrgiz as well. Splitting his forces, the great Khan struck north with fifteen thousand warriors, while Taybuga and Chila led another ten thousand each against the fierce Naiman.
The Nestorian christians of the Naiman attempted to fight back, but in both the mountains and the plains they were defeated. Cut down by the skilled horse-warriors. To their north, the Kyrgiz were all but defeated. In 1184 A.D. Genghis Khan took control of the cities Luo-Si and Ke-wo-luo-hai in the Tangut territories, even as his generals continued to wage an uncompromising war against the naiman tribes. The Kyrgiz submitted to the great Khan in february of that year and by april the two tribes of the Naiman did so as well. The last of the powerful tribes of mongolia proper were now defeated. Yet even as the blood began to dry from his mighty sword, Temujin looked farther west, towards the Altai lands just beyond the Ob river. Mongolia belonged to the Great Khan, but he was not content to settle, not yet.. perhaps not ever.
In 1184 A.D. Temujin took control over the Kyrgiz and the Naiman tribes, his gaze soon straying west towards the Altai lands.
Two months was all he gave his troops, before they once more rode out across the open land, swords gleaming and the words of war on their lips. The Altai didn't know what hit them. The mongol horde swept over their land, slaying all who resisted and quickly took control of the land, burning villages and enslaving the survivors. Many Altai fled behind their walled cities, but this only stalled the inevitable. Genghis Khan soon claimed victory and took the land for his own, forcing most of the Altai into servitude. It was Temujins opinion that the Altai were cowards and only by living in chains could they gain the fortitude and courage to one day become true mongols.
Genghis surveyed his domain and found himself unsatisfied. Some say that Genghis Khan did not even ponder stopping at this point, his food becoming the glories of war and his thirst that for blood. Yet Genghis Khan was no fool, he knew that his next challenge would either be the mighty Jin Empire or the powerful Qara-Khitai. After much thought, Genghis Khan and his general Belgutai decided that it was his duty to strike against the Uzbehk lands stolen by Yelq Zulkhu of the Qara-Khitai. Yet the time was not yet right, Journeying back to the interior of Mongolia, Genghis Khan began to set down his laws and began what became known as the years of training. For eight long years, his mongol warriors trained, practicing in minor raids east, west and south. He promoted generals and transformed the chaos of the mongol horde into an organized force of destruction obediant to his will.
