The 5th century, spanning from the year 401 to 500, was a significant period in history marked by the decline of the Western Roman Empire. This era saw the rise of various barbarian tribes, including the Visigoths and Vandals, who invaded and settled in former Roman territories. In the East, the Byzantine Empire began to emerge as a powerful entity, preserving much of Roman culture and governance. Additionally, this century witnessed the spread of Christianity, which became increasingly influential in shaping European societies and cultures.
