In 477 AD, the Western Roman Empire was in decline, facing invasions and internal strife. This period marked the gradual fall of Roman authority in Europe, as various tribes, including the Visigoths and Ostrogoths, began to establish their own kingdoms in former Roman territories. During this time, the Eastern Roman Empire, also known as the Byzantine Empire, continued to thrive, maintaining its capital in Constantinople. The division between the Eastern and Western Roman Empires became more pronounced, setting the stage for the eventual rise of medieval Europe.
