The monarch had wide autocratic powers, but was surrounded and advised by a permanent council of magnates and prelates. The court, chancellery and administration were rough copies of those of Constantinople. The Code named the administrative hierarchy as following: "lands, cities, župas and krajištes", the župas and krajištes were one and the same, with the župas on the borders were called krajištes ("frontier march"). The župa consisted of villages, and their status, rights and obligations were regulated in the constitution. The ruling nobility possessed hereditary allodial estates, which were worked by dependent "sebri", the equivalent of Greek "paroikoi"; peasants owing labour services, formally bound by decree. The earlier title of "župan" was abolished and replaced with the Greek "kephale" ("kefalija", "head, master").
