Leo IV the Khazar (Greek: Λέων Δ΄ ὁ Χάζαρος, Leōn IV 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 caesar the next year, in 751. When Constantine V died in September 775, while campaigning against the Bulgarians, Leo IV became senior emperor on 14 September 775. In 778 Leo raided Abbasid Syria, decisively defeating the Abbasid army outside of Germanicia. Leo died on 8 September 780, of tuberculosis. He was succeeded by his son Constantine VI, who was eventually overthrown by his wife Irene, who installed herself as empress.

History
Leo IV was born in 750AD, to Emperor Constantine V and his first wife, Empress Tzitzak. Because his mother was a Khazar, Leo was given the epitaph 'the Khazar'. Leo was elevated to co-emperor in 751, while still an infant. Leo became emperor on 14 September 775, after Constantine V died while campaigning against the Bulgarian Empire.

Leo was by this point suffering from tuberculosis, which, combined with the infancy of his son, Constantine VI, gave two of Leo's half-brothers, the caesares Nikephoros and Christopher, hope of attaining the throne. These hopes were crushed when, in 776, Leo elevated Constantine to caesar, declaring him to be his successor. Shortly after this, Nikephoros and Christopher were discovered conspiring against Leo. Although public opinion supported the execution of both of them, Leo chose to pardon them, although he did exile several other plotters to Cherson.

Leo raided the Abbasids in 778, invading Syria with about 100,000 men, made up of the armies of the multiple themes, including the Opsikion Theme, led by Gregory, the Anatolic Theme, led by Artabasdos, the Armeniac Theme, led by Karisterotzes, the Bucellarian Theme, led by Tatzates, and the Thracesian Theme, led by Lachanodrakon. Lachanodrakon sieged Germanicia for a time, before he were bribed to raise the siege, and then began to raid the surrounding countryside. The Abbasids attacked Lachanodrakon while he was raiding, but were decisively defeated by several Byzantine armies. The Byzantine generals who led troops during this battle were given a triumphal entry when they returned to Constantinople. A number of Jacobites were taken from Syria and forcibly resettled in Thrace. The next year, in 779, Leo successfully repelled an attack by the Abbasids against Asia Minor.

Leo died of a violent fever on 8 September 780. He was succeeded by his son Constantine, with his wife Irene as his regent. In 797, after Constantine had ruled for 17 years, Irene had him blinded, and became empress.
