君士坦斯二世
After a period of Vandal rule, 469–477, Syracuse and the island was recovered for Roman rule under Odoacer, 476–491 and Theodoric the Great, 491–526, by Belisarius for the Byzantine Empire (31 December 535). From 663 to 668 Syracuse was the seat of the Greek-speaking Emperor Constans II, as well as a capital of the Byzantine (Eastern Roman) Empire and metropolis of the whole Sicilian Church. Constans II was assassinated when his plans to permanently replace the Byzantine capital of Constantinople with Syracuse became suspected.
