Dušan's Code (Serbian Cyrillic: Душанов законик, Dušanov zakonik, known historically as Закон благовјернаго цара Стефана – Law of the pious Emperor Stefan) is a compilation of several legal systems that was enacted by Stefan Uroš IV Dušan of Serbia in 1349. It was used in the Serbian Empire and the succeeding Serbian Despotate. It is considered an early constitution, or close to it; an advanced set of laws which regulated all aspects of life.
