There is no evidence that the final emperor, Constantine XI, ever repudiated the union achieved at Florence in 1439. Many of his subjects had chastized him as a traitor and heretic while he lived and he, like many of his predecessors before him, died in communion with the Church of Rome. Nevertheless, Constantine's actions during the Fall of Constantinople and his death fighting the Turks redeemed the popular view of the Palaiologan dynasty. The Greeks forgot or ignored that Constantine had died a "heretic", many considering him a martyr. In the eyes of the Orthodox church, Constantine's death sanctified him and he died a hero. As Ottoman rule continued, many Greeks dreamed of a day when a new emperor would once more rule a sizeable Greek domain. Some even believed that Constantine XI would return to rescue them, that he wasn't actually dead but merely asleep, awaiting a call from the heavens to return and restore Christian control over Constantinople.
