The Byzantine Empire evolved from the Eastern Roman Empire. Following the fall of the Western Roman Empire in 476 AD, the Eastern Roman Empire continued to thrive, with its capital at Constantinople, established by Emperor Constantine I in 330 AD. The Byzantine Empire maintained Roman law and governance while integrating Greek culture and Christian faith, distinguishing itself from its western counterpart. Over the centuries, it became known for its unique blend of classicism and Christianity, as well as significant contributions to art, architecture, and law. The Byzantine Empire persisted until the fall of Constantinople in 1453, leaving a lasting legacy on European civilization.
