Some nobles with the last name Palaiologos remained in Ottoman Constantinople, and even prospered in the immediate post-conquest period. In the decades after 1453, Ottoman tax registers show a consortium of noble Greeks co-operating to bid for the lucrative tax farming district including Constantinople and the ports of western Anatolia. This group included names like "Palologoz of Kassandros" and "Manuel Palologoz". This group stood in close contact with two powerful viziers, Mesih Pasha and Hass Murad Pasha, both of whom were reportedly nephews to Constantine XI Palaiologos and had been forced to covert to Islam after Constantinople's fall, as well as with other converted scions of Byzantine and Balkan aristocratic families like Mahmud Pasha Angelović, forming what the Ottomanist Halil İnalcık termed a "Greek faction" at the court of Mehmed II.
