Timur or Tamerlane (1325 - 17–19 February 1405) was a Turco-Mongol conqueror who founded the Timurid Empire in and around modern-day Afghanistan, Iran, and Central Asia, becoming the first ruler of the Timurid dynasty. An undefeated commander, he is widely regarded as one of the greatest military leaders and tacticians in history, as well as one of the most brutal and deadly. Timur is also considered a great patron of art and architecture as he interacted with intellectuals such as Ibn Khaldun, Hafez, and Hafiz-i Abru and his reign introduced the Timurid Renaissance.
Born into the Mongolic-Turkic Barlas confederation in Transoxiana (in modern-day Uzbekistan) in the 1320s, Timur gained control of the western Chagatai Khanate by 1370. From that base, he led military campaigns across Western, South, and Central Asia, the Caucasus, and Southern Russia, defeating in the process the Khans of the Golden Horde, the Mamluks of Egypt and Syria, the emerging Ottoman Empire, and the late Delhi Sultanate of India and emerging as the most powerful ruler in the Muslim world. From these conquests, he founded the Timurid Empire, which fragmented shortly after his death. He spoke several languages, including Chagatai, an ancestor of modern Uzbek, Mongolic and Persian, in which he wrote diplomatic correspondence.
Timur was the last of the great nomadic conquerors of the Eurasian Steppe, and his empire set the stage for the rise of the more structured and lasting Islamic gunpowder empires in the 16th and 17th centuries. Timur was of both Turkic and Mongol descent, and, while probably not a direct descendant on either side, he shared a common ancestor with Genghis Khan on his father's side, though some authors have suggested his mother may have been a descendant of the Khan. He clearly sought to invoke the legacy of Genghis Khan's conquests during his lifetime. Timur envisioned the restoration of the Mongol Empire and according to Gérard Chaliand, saw himself as Genghis Khan's heir.
