What if Constantinople had never fallen to the Turks?

[G. Septimus]

The Balkans, will either revolt, or be captured by the Turks, well, the Fall of Constantinople
could'nt be stopped (except if the earlier Ottoman campaigns could be halted, and the Crusader lands at
Palestine would'nt be taken, it would'nt happen)

[A Very Super Market]

You don't get it, in 1543, the Byzantine Empire was reduced to only Constantinople. The Ottomans already took the lands East and West of them, Bulgaria and Anatolia.

[G. Septimus]

So, if only Constantinople, we can only stop the fall of the Empire almost 160 years before(1291)
when the Crusader states fallen, and been taken by the Muslims, the Simple truth is:
THE FALL OF CONSTANTINOPLE CAN'T BE PREVENTED!!!!!!!

That's not quite right. Most of Morea (Peloponnese) was still under Byzantine control in 1453. Some of Constantine XI's advisers urged him to flee to that province to escape the fall of the city and continue the fight, but he refused.
