Founder and first khan of the Mongol Empire (1206-1227); born Temujin, he united the Mongol tribes and built the largest contiguous land empire in history.
Early Life
Temujin was born around 1162, the eldest child of Yesugei, a chieftain of the Borjigin clan, and his wife Hö'elün, in the Khentii Mountains of present-day Mongolia, near the Onon River. His father was poisoned by Tatars when Temujin was about nine, and his clan abandoned the family, leaving them in severe poverty. Temujin survived by fishing and foraging, was captured for a time by the Tayichiuds and escaped, and killed his half-brother Bekter in a dispute over food. He married Börte around 1178, and when she was captured by the Merkit tribe he rescued her with the help of his allies. These early hardships shaped his reliance on loyalty and merit rather than birth.
Education
Temujin received no formal education; the Mongols of his time had no written language of their own. He learned warfare, horsemanship and leadership in the steppe, and as ruler he ordered the adoption of the Uyghur script for writing Mongolian, employed Uyghur, Chinese and Muslim administrators and specialists, and built an administration that recorded laws, taxes and communications.
Career
Temujin rose to power by building alliances and defeating rival Mongol leaders, including his former friend Jamukha, whom he defeated in the early 1200s. In 1206 a kuriltai, an assembly of the Mongol tribes, proclaimed him Genghis Khan, meaning universal ruler. He then turned outward: he campaigned against the Western Xia from 1207, attacked the Jin dynasty in 1211 and captured its capital Zhongdu, present-day Beijing, in 1215, and in 1219 launched a campaign against the Khwarezmian Empire in Central Asia after its ruler executed Mongol merchants and an ambassador. His armies, organised into units of ten, a hundred, a thousand and ten thousand under commanders chosen for merit, used mobility, discipline, siege engineering learned from Chinese and Muslim specialists, and intelligence gathering. Alongside conquest he built institutions: the Yassa code of law, the yam postal relay system, a policy of religious tolerance, and support for trade. He died in August 1227 during a final campaign against the Western Xia, and his burial place was kept secret. His empire was divided among his four sons, and his third son Ögedei was elected his successor in 1229.
Achievements
Genghis Khan's central achievement was to unite the warring Mongol tribes into a single people and to build from them an empire that, at its height, stretched from the Pacific to Eastern Europe, the largest contiguous land empire in history. He did this through a meritocratic army organised on the decimal system, in which promotion depended on ability rather than birth, and through a code of law, the Yassa, and an administration that used the Uyghur script and a relay postal system, the yam. His campaigns conquered the Western Xia and the Jin dynasty in northern China and the Khwarezmian Empire in Central Asia. He also promoted trade along the Silk Road, protected merchants, and practised religious tolerance. After his death in 1227 his sons and grandsons continued to expand the empire he had founded.

Legacy
Genghis Khan is remembered in two very different ways. In Mongolia he is revered as the founding father of the nation, and he was posthumously deified there. Across Eurasia his conquests caused immense destruction and loss of life, and his name became a byword for ruthless warfare. At the same time, historians credit his empire with unifying much of Eurasia under a single administration, securing the Silk Road, spreading technology and ideas, and creating institutions that his successors developed. The exact year of his birth is uncertain, sources giving a range between 1155 and 1167, and the exact day and cause of his death are also uncertain. Because the surviving sources, written in more than a dozen languages across Eurasia, disagree on many details of his life, this profile records only the points on which the sources broadly agree and notes where they differ.
Contributions
Genghis Khan's contribution was to unite the Mongol tribes and to found an empire that connected East and West under a single administration. His army, his legal code, his postal system and his policies on trade and religious tolerance shaped the political map of Eurasia for generations, and the empire he founded continued to expand under his sons and grandsons after his death.
