AI overview
Leo IV (ruled 775-780) was a Byzantine emperor whose mother was a Khazar princess, making him the only Byzantine ruler with Central Asian ancestry. His reign is historically significant because it marked a period of relative stability in the Byzantine Empire and he continued his parents' policies of religious iconoclasm (the destruction of religious images).

Leo IV the Khazar (Greek: Λέων ὁ Χάζαρος, romanized: Léōn ho Khazaros; 25 January 750 – 8 September 780) was Byzantine emperor from 775 to 780 AD. He was born to Emperor Constantine V and Empress Tzitzak in 750. He was elevated to co-emperor in the next year, in 751, and married to Irene of Athens in 769. When Constantine V died in September 775, while campaigning against the Bulgars, Leo IV became senior emperor. In 778 Leo raided Abbasid Syria, decisively defeating the Abbasid army outside of Germanikeia. Leo died on 8 September 780, of tuberculosis. He was succeeded by his underage son Constantine VI, with Irene serving as regent.
