The Ottoman expansion in the north of the Danube towards the end of the 15th century led to significant territorial losses for the Principality of Moldavia. Chilia and Cetatea Albă were occupied by the Ottomans, alienated and passed under the direct administration of the Ottoman Gate. According to the Islamic tradition, which played an important role in the social and political life of the Ottoman Empire, the conquered lands became a territory of the padâșah, part of the state. The Ottoman land system, known as the „timariot regime”, was one of the fundamental institution in the state. Apart from the timariot system, based on conditional property, in the territories subjected by the Ottoman Gate, there is also an unconditional property, called mulk. Also, in the Ottoman Empire, there were certain properties designed to satisfy the material needs of religious institutions and the muslims charities. These are known as vakif.
