When the Ottomans were gaining a firm foothold in the region, Albanian towns were organised into four principal sanjaks. The government fostered trade by settling a sizeable Jewish colony of refugees fleeing persecution in Spain. The city of Vlorë saw passing through its ports imported merchandise from Europe such as velvets, cotton goods, mohairs, carpets, spices and leather from Bursa and Constantinople. Some citizens of Vlorë even had business associates throughout Europe.
