  • Battle of Nahāvand: The Rashidun army (30,000 men) under Sa`d ibn Abi Waqqas defeats the Persians at Nahāvand (modern Iran). The Persian cavalry, full of confidence, mounts an ill-prepared attack. The Arabs retreat to a safe area, where they outmanoeuvre and destroy the Persians in a narrow mountain valley.

  • Emperor Taizong of the Tang dynasty issues a decree throughout China, that increases the punishment for men who deliberately inflict injuries upon themselves (most commonly breaking their own legs) in order to avoid military conscription.

  • Taizong supports a revolt by Turkic tribes against the rebellious Tu-lu Qaghan of the Western Turkic Khaganate.
  • Empress Kōgyoku ascends to the throne of Japan, after her husband (and uncle) Emperor Jomei's death in 641.
