What was the Byzantine Empire?

The Byzantine Empire, often considered the eastern continuation of the Roman Empire, was a medieval state centered around the capital city of Constantinople (modern-day Istanbul) that endured for over a thousand years. Its foundation is traditionally dated to 330 AD when Emperor Constantine the Great established Constantinople as the new capital of the Roman Empire.

This empire reached its zenith under Emperor Justinian I (527-565 AD), who sought to reclaim the territories of the Western Roman Empire and codify Roman law in the Corpus Juris Civilis. 

Despite facing various external threats, such as invasions by the Huns, Persians, and later the Arab Muslims, the Byzantines managed to preserve their civilization, adapting and blending Roman, Greek, and Christian traditions.
