Land : The lands under the possession of the state should be evaluated in four sections in the Seljuk State.
1) Fief Lands: It is the land the taxes of which are collected to the ruler in the Seljuk State. The Seljuk sultans could possess all the fief lands and the other lands that were not under private property. For example, they could enfeoff these lands upon their arbitration. However, he would preserve the fief lands especially for him and he would donate them to his relatives.
2) Fief-Holding System: This system was the abandonment and allocation of some state incomes pertaining to specific places to the commanders, soldiers and the celebrities in return for their services and salaries. The feoffs pertaining to the emirs and statesmen were valid as long as their term of office. When any of them was dismissed from his office, his feoff would be confiscated. When the ruler changed, all the patents of the feoffs would also change. The feoff-holders could not receive more income than the definite amount of income specified for him.
3) Property (Private) Lands: The landowner of this type would have a full property right on his properties and lands. This land could not be confiscated, and it would be inherited to his children in accordance with his demands. The landowner could sell, donate or dedicate his lands to any foundation.
4) Foundation lands: It was the lands allocated among the incomes from the lands belonging to the state of private property so as to cover the expenditures of scientific or social schools. The incomes of these foundation lands were used for the maintenance of the mosques, theological schools, hospitals and the other buildings that were constructed with the purposes of public benefit and the compensation of the staff working in these institutions.
