Timur was born in Transoxiana near the city of Kesh (modern Shahrisabz, Uzbekistan), some 80 kilometres (50 mi) south of Samarkand, part of what was then the Chagatai Khanate. His name Temur means "Iron" in the Chagatai language, his mother-tongue (cf. Uzbek Temir, Turkish Demir).. He was a member of the Barlas, a Mongolian tribe that had been turkified in many aspects.
