Constantine XI Palaiologos

Constantine XI Palaiologos was the last Byzantine emperor, ruling from 1449 until the Ottoman conquest of Constantinople in 1453. With only limited western assistance, he organised the defence of the city against Mehmed II and died during the final assault. His body was never securely identified, helping to create later legends about his survival and eventual return.

Mika Waltari’s The Dark Angel is among the best-known novels to place Constantine within the final siege, presenting the emperor through the eyes of characters caught between Byzantine, Latin and Ottoman worlds. Fiction often turns him into the embodiment of a dying empire, but the most effective portrayals retain the immediate political, religious and military divisions that constrained the defence of Constantinople.
