Basilika

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and adapt the Emperor Justinian I's Corpus Juris Civilis code of law issued between 529 and 534 which had become outdated.

However, by the 9th century the use of Latin was obsolete, which in turn made the Corpus Juris Civilis code hard to use for Greek speakers, even in the capital of Constantinople.

There was vast confusion amongst judges as to which legal documents they should refer to (Justinian's Codex or other books of law which had been written in the ensuing centuries).

Additionally, Justinian's Codex had officially stripped the legislative branch of its authority, making it hard for judges to know which law codes they should follow.

In addition, the Basilika and similar legal reform projects helped retain and reinvigorate the Romanitas, or Roman-ness, of the Byzantine Empire.

[1][3][4] The Basilika also presents itself as a connection back to earlier times before the period of Iconoclasm, lending the Macedonian dynasty a sense of religious legitimacy.
