Answer:
They Byzantine legal system is best described as a combination of government laws and local customs.
Step-by-step explanation:
Byzantine law was essentially a continuation of Roman law with greater Christian influence. Most sources define Byzantine law as the Roman legal traditions that began after the reign of Justinian I in the sixth century and ended with the fall of Constantinople in the fifteenth century.
Although during and after the European Renaissance Western legal practices were strongly influenced by the Justinian Code - Corpus iuris civilis - and Roman law during the classical era, Byzantine law had substantial influence on Western traditions during the Middle Ages and eras later.
The most important work of the Byzantine law was the Ecloga, issued by Leo III, the first Roman-Byzantine legal code written in Greek instead of Latin. Shortly after, the Agrarian Law was established that regulated the legal norms outside the cities. Although the Ecloga was influential throughout the Mediterranean, and also in Europe, due to the importance of Constantinople as a commercial center, the Agrarian Law was a fundamental influence on the Slavic legal traditions, including those of Russia.
