Genghis Khan was born in north central Mongolia and named "Temujin".Temujin was born with a blood clot in his hand, a sign in Mongol folklore that he was destined to become a leader. His father Yesukhei and mother Hoelun, taught him the grim reality of living in turbulent Mongol tribal society and the need for alliances. When he was 9, his father took him to live with the family of his future bride, Borte. On the return trip home, Yesukhei encountered members of the rival Tatar tribe, who invited him to a conciliatory meal, where he was poisoned for past transgressions against the Tatars. So on his father was died, Then the pressure on the family was great, and in a dispute over the spoils of a hunting expedition. At 16, he married Borte. Borte was kidnapped by the rival Merkit tribe and given to a chieftain as a wife.Genghis Khan was able to rescue her and soon after she gave birth to her first son, Jochi. He had four sons and many other children with other wives. When he was about 20, he was captured in a raid by former family allies. He escaped with the help of a sympathetic captor and joined his brothers and several other clansmen to form a fighting unit. Temujin began his slow ascent to power by building a large army of more than 20,000 men. He set out to destroy traditional divisions among the various tribes and unite the Mongols under his rule. Through a combination of outstanding military tactics and merciless brutality, Genghis Khan avenged his father's murder by decimating the Tatar army and ordered the killing of every Tatar male less than 3 feet tall. And had all the Taichi'ut chiefs boiled alive. By 1206, He also had defeated the powerful Naiman tribe, thus giving him control of central and eastern Mongolia.The early success of the Mongol army owed much to the brilliant military tactics of Genghis Khan and his understanding of his enemies' motivations.The well-trained Mongol army of 80,000 fighters coordinated their advance with a sophisticated signaling system of smoke and burning torches. Every soldier was fully equipped with bow, arrows, shield, dagger, and lasso. He also carried large saddlebags for food, tools, and spare clothes.The saddlebag was waterproof and could be inflated to serve as a life preserver when crossing deep and swift-moving rivers. Following the victories over the rival Mongol tribes, other tribal leaders agreed to peace and bestowed on Temujin the title of "Genghis Khan," which means "universal ruler." Genghis Khan wasted no time in capitalizing on his divine stature. Although the campaign against the Jin Dynasty lasted nearly 20 years, Genghis Khan's armies were also active in the west against border empires and the Muslim world. Initially, Genghis Khan used diplomacy to establish trade relations with the Khwarizm Dynasty, a Turkish-dominated empire that included Turkestan, Persia, and Afghanistan. Genghis Khan died in 1227 soon after the submission of the Xi Xia. Before his death, Genghis Khan bestowed supreme leadership to his son Ogedei, who controlled most of eastern Asia, including China.The rest of the empire was divided among his other sons.
