Answer:
Both empires shared like laws and traditions.
Step-by-step explanation:
The Byzantine Empire was the society that developed in the eastern Roman Empire after the fall of the western Roman Empire. Its capital was Constantinople.
Regarding traditions, there was a split in Christianity between East and West, called the Great Schism: the Church in the West became the Roman Catholic Church, while the Eastern Orthodox Church continued to grow in the East, based in the city of Constantinople.
Considering laws, the laws of the Byzantine Empire, called Justinian Code, was based on the Twelve Tables of Roman law. In that matter, these laws became a basis for laws in many European nations.
