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.
