Genghis Khan
Genghis Khan probably[2] 1162–1227), his original name, Temüjin, was the founder, ruler and emperor of the Mongol Empire, the largest contiguous empire in history. He came to power by uniting many of the nomadic tribes of northeast Asia. After founding the Mongol Empire and being proclaimed "Genghis Khan", he started the Mongol invasions and raids of the Kara-Khitan Khanate, Caucasus, Khwarezmid Empire, Western Xia and Jin dynasties. By the end of his life, the Mongol Empire occupied a substantial portion of Central Asia and China. #### Beyond his great military accomplishments, Genghis Khan also advanced the Mongol Empire in other ways. He decreed the adoption of the Uyghur script as the Mongol Empire's writing system. He also promoted religious tolerance in the Mongol Empire, and created a unified empire from the nomadic tribes of northeast Asia. Present-day Mongolians regard him highly as the founding father of Mongolia.
Uniting the confederations
The Central Asian plateau (north of China) around the time of Temüjin (the early 1200s) was divided into several tribes or confederations, among them Naimans, Merkits, Uyghurs, Tatars, Mongols, and Keraits, that were all prominent in their own right and often unfriendly toward each other as evidenced by random raids, revenges, and The main opponents of the Mongol confederation (traditionally the "Mongols") around 1200 were the Naimans to the west, the Merkits to the north, Tanguts to the south, and the Jin and Tatars to the east. By 1190, Temüjin, his followers, and their advisors, had united the smaller Mongol confederation only. In his rule and his conquest of rival tribes, Temüjin broke with Mongol tradition in a few crucial ways. He delegated authority based on merit and loyalty, rather than family ties.
Politics
The Mongol Empire was governed by a civilian and military code, called the Yassa, created by Genghis Khan. The Mongol Empire did not emphasize the importance of ethnicity and race in the administrative realm, instead adopting an approach grounded in meritocracy. The exception was the role of Genghis Khan and his family. The Mongol Empire was one of the most ethnically and culturally diverse empires in history, as befitted its size.
Religion
Genghis Khan's religion is widely speculated to be Shamanism, which was very likely among nomadic Mongol-Turkic tribes of Central Asia. But he was very tolerant religiously, and interested to learn philosophical and moral lessons from other religions. To do so, he consulted Christian missionaries, Muslim merchants, and the Taoists.
