The Battle of Ankara or Angora was fought on 20 July 1402 at the Çubuk plain near Ankara, between the forces of the Ottoman sultan Bayezid I and the emir of the Timurid Empire, Timur. The battle was a major victory for Timur, and it led to the Ottoman Interregnum.

Timur, also known as Tamerlane, 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.
