The Eastern Roman Empire, also called the Byzantine Empire, was the Roman Empire's eastern half that stayed strong even after the west crumbled. They lasted for over a thousand years until the Ottomans came in and kicked their ass.
The Eastern Roman Empire was like the cool kid in school who never got bullied.
Byzantium was the last man standing when the rest of Rome got knocked out.
The Ottomans were like the new bully who showed up and said, 'You're not cool anymore.'
