Eastern Roman Empire
The Byzantine Empire was the Roman Empire’s eastern part, still going strong while the west fell apart. They lasted for a thousand years until the Ottomans came and gave them the worst beatdown ever.
Byzantium was the only Roman kid who stayed in school while the rest got expelled.
They lasted longer than your mom's Netflix subscription.
The Ottomans gave them a beatdown so hard, they went from A to F in one day.
