Following the fall of Patras, the majority of the Roman cities in the Peloponnese Peninsula surrendered their keys to the hands of Julian. Just less than a year after the decease of his honourable Emperor of All Romans Constantine XI, the Peninsula that took his entire life to recover fell into the hands of another man. And with this new conquest, almost ninety percent of Constantinople's sources for taxation and manpower is now lost.
Looking at the still ongoing political struggles and conflicts between the two factions in Constantinople, this came as a devastating, actually, disastrous news for them, especially for Thomas Palaiologos who relied heavily upon the resources of the Despotate of Morea to contest with his brother Demetrios who had a more solid foundation inside the city of Constantinople.
