Leo IV (the Khazar)

Leo IV, known as "the Khazar," was a Byzantine Emperor who ruled from 775 to 780 AD. He earned his nickname because of his close ties to the Khazar Empire, a powerful Jewish-ruled state in Eastern Europe. Leo IV was notable for strengthening the empire’s defenses and promoting Christianity. His reign was marked by efforts to consolidate power and manage diplomatic relations, including with the Khazars. Leo's leadership helped stabilize the Byzantine Empire during a challenging period, and his connection to the Khazar Empire highlights the diverse interactions between different cultures and states in that era.
