The Constitutions of Melfi, also known as the Liber Augustalis, were a landmark set of laws issued by Frederick II in August 1231 for the Kingdom of Sicily.12

These laws represented a significant moment in legal history, as they were the first administrative law of a European state to be codified since the 6th-century reign of the Byzantine emperor Justinian I. Drawing from the study of Roman law and canon law, the Constitutions aimed to unify the kingdom's diverse elements under strong royal leadership.12

Key aspects of the legislation included:
* Centralization: The codes anticipated enlightened absolutism by centralizing state power.1
* Judicial Reform: They provided for improved royal administration, increased efficiency in the courts, and the rationalization of civil and criminal procedures.2
* Public Welfare: The laws addressed public health, medical education, and environmental concerns such as air and water pollution.2
