I'm not saying that Florence helped or didn't help. The city was doomed anyway.
But let me address a few things while I'm at it:
>Schism happen
It's not a schism strictly speaking if eucharistic communion is kept. And eucharistic communion was kept until 1204 since Alexandria, Antioch, and Jerusalem kept communion with both Rome and Constantinople. If by "schism" you have in mind the "Great Schism", modern scholars pretty much all agree that 1204 is a better date.
>massacre latin
And the Latins paid it back with the sack of Thessalonica a few years later.
>despite being condemned by the Pope, the 4th crusade end up sacking Constantinople due to various events
"Condemned" by the Pope? Did the reductio Graecorum vanish from your memory?
