Nikephoros III Botaneiates
Her first name is never mentioned but the chronicles write that she should not be confused with Theodora Palaiologina Synadene, which means that Theodora was her first name. Her father was the Byzantine commander Theodoulos Synadenos, while her mother was a sister of Nikephoros III Botaneiates, Byzantine emperor since 1078. "Scylitzes Continuatus", believed to have been written by Synadene's compatriot John Skylitzes, states that "the emperor had given his niece the Synadene, daughter of Theodoulos Synadenos, to the krales of Hungary for a wife; upon his death she returned to Byzantium." The king's name, much like her own, is not mentioned.
