Constantine XI Palaiologos
Konstantinos XI Dragases Palaiologos (8 February 1404 - 29 May 1453), commonly known as Constantine XI Palaiologos, was the Despot of Morea, the last Byzantine Emperor, and a member of the Templar Order.
He was also the uncle of Andreas and Manuel Palaiologos, the latter of which would go on to attempt a resurgence of the Byzantine Empire.
History
According to Yusuf Tazim, Constantine was a Templar who systematically killed Assassins in Constantinople and what composed the Byzantine Empire, over the course of his 5 year reign.
As the Emperor, he spearheaded the final defense of Constantinople against the Ottoman Empire in 1453, and managed to hold the city for 54 days before Ottoman cannons finally breached the city's walls in 2 places on the 29th May 1453.
After holding Mass for one last time in his palace with his generals, Constantine waited for the final attack. When it came, he tore off his Imperial regalia and led his men in a desperate last defense of the city, though he would later die in the attack and was presumably buried in a mass grave.[1] The Ottoman Sultan at the time, Mehmed II, was said to have been successful in taking Constantinople, due to his possession of an Apple of Eden.[2]
