The newly conquered region was initially the patrimonial domain of the powerful marcher-lord () Turahan Bey (died 1456) and of his son Ömer Bey (died 1484) rather than a regular province. Turahan and his heirs brought in settlers from Anatolia (the so-called "Konyalis", or "Koniarides" in Greek, since most were from the region around Konya) to repopulate the sparsely inhabited area, and soon, Muslim settlers or converts dominated the lowlands, while the Christians held the mountains around the Thessalian plain. Banditry was endemic, and led to the creation of the first state-sanctioned Christian autonomies known as s, the earliest and most notable of which was that of Agrafa.
