Temujin was a member of the Qiyan Tribe of Mongolia. He was born in the upper reaches of the Onan River [wò nán hé] (today's Onen River) in Mobei (today's Kent Province of Mongolia). He lost his father in his early years and was expelled by hostile tribes and defected to the Kelei Tribe. After gathering his tribe, he was elected as the Khan of the Mongolian Qiyan tribe in 1189. After a series of wars, he basically unified the tribes on the Mongolian plateau in 1204. In 1206, he established the Great Mongolian Kingdom at the source of the Onan River, the emperor (Khan). After the founding of the People's Republic of China, Temujin implemented a unified military and political system where all people were soldiers, established the Qinshe Guard Army, promulgated the first written code in Mongolian history, "Dazhasa", and translated and unified the Mongolian language. During his reign, Temujin launched many southern and western expeditions, occupying large areas of the Jin Dynasty in East Asia and destroying countries such as Xixia, Western Liao and Khwarezm in Central Asia. His conquests reached as far as the Black Sea coast. In 1227, Temujin died of illness at the age of sixty-six. Before his death, he decided on the strategy of "alliance with the Song Dynasty to destroy the Jin Dynasty". After his death, he was secretly buried in Qichang Valley. After the establishment of the Yuan Dynasty, he was given the posthumous title of "Emperor Fa Tian Qi Yun Sheng Wu" and the temple name Taizu.
