The Byzantine Empire traces its beginnings to the year 330 when Emperor Constantine split the Roman Empire into a western and eastern half. This eastern half, or Byzantine Empire as it was later called, remained the strongest power in Europe throughout the rest of late antiquity and even during parts of the middle ages. It survived until 1453, when its capital Constantinople fell to the Ottoman Turks. This guide provides lists of resources for researchers.
