The fall of the Roman Empire was a complex process influenced by a combination of internal and external factors. Internal causes include political instability, economic crises, corruption, and the division of the empire into East and West. External factors encompass barbarian invasions, such as those led by the Visigoths, Vandals, and Huns, which put immense pressure on the weakening empire. The sack of Rome in 410 CE by the Visigoths and the eventual deposition of the last Roman emperor in 476 CE are often cited as significant events symbolizing the fall. Additionally, the empire's size, administrative challenges, overextension, and military weaknesses contributed to its decline. The fall of the Roman Empire marked a pivotal moment in history, leading to significant shifts in power, culture, and the rise of new civilizations in Europe.
