What century is the fall of the Western Roman Empire?

Its fall dates back to the 5th century. Then in Europe there were many changes associated with the movement of barbarian tribes and the invasion of the Huns. So, due to constant wars on the borders and a clash with the Huns, Rome was finally weakened, which became the reason for its fall in 476. After that, the first barbarian states began to emerge on the territory of Europe: the kingdom of the Vandals, Visigoths, Ostrogoths, etc.
