Timur (Chagatay: تيمور Temür, lit. ‘Iron’; 9 April 1336 – 17–19 February 1405), later Timūr Gurkānī (Chagatay: تيمور کورگن Temür Küregen), 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. As an undefeated commander, he is widely regarded as one of the greatest military leaders and tacticians in history. Timur is also considered a great patron of art and architecture as he interacted with intellectuals such as Ibn Khaldun and Hafiz-i Abru and his reign introduced the Timurid Renaissance.
