How did the Byzantine empire differ from the western Roman empire?

The Byzantine Empire was the continuation of the Roman Empire in the East after the fall of the Western Roman Empire in 476 CE. The Byzantine Empire was centered in Constantinople (modern-day Istanbul) and was Greek-speaking and Eastern Orthodox in culture and religion. It was more centralized than the Western Roman Empire, with a strong bureaucracy and a powerful military. The Byzantine Empire also had a different legal system, with a focus on religious law, and a different currency. The Byzantine Empire was also more tolerant of different religions than the Western Roman Empire, and had a more diverse population.
