The Basilika was a collection of laws completed c. 892 CE in Constantinople by order of the Byzantine Emperor Leo VI the Wise during the Macedonian dynasty. This was a continuation of the efforts of his father, Basil I, to simplify and adapt the Emperor Justinian I's Corpus Juris Civilis code of law issued between 529 and 534 which had become outdated. The term "Basilika" comes from Greek: Τὰ Βασιλικά meaning "Imperial Laws" and not from the Emperor Basil's name, which though shares the etymology "imperial".
