Basilika

Leo VI (right) and Basil I (left), from the 12th-century Madrid Skylitzes.

The Basilika (Greek: τὰ βασιλικά, romanizedta basiliká, "the imperial [laws]") was a collection of laws completed c. 892 AD 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and adapt the Emperor Justinian I's Corpus Juris Civilis code of law issued between 529 and 534 which had become outdated.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 comes from the Greek adjective Basilika meaning "Imperial (laws or enactments)" and not from the Emperor Basil's name; both sharing a common etymology from the term Basileus.
