Tzitzak

Khazar princess, daughter of Khagan Bihar. Tzitzak became a Christian under the baptismal name Eirene and married the Byzantine prince Constantine in the mid 730's. He would later become Emperor Constantine V. Their son, who would inherit the throne as Leo IV, was nicknamed "The Khazar."

Byzantine sources report that the style of Tzitzak's wedding gown created a new fashion for male robes called tzitzakion.
