The document discusses the fall of Rome from several perspectives:
1) The last attempts to save Rome by Theodosius who split the empire in half but it was still difficult to rule.
2) The migration of Germanic tribes into Roman lands due to pressures from the Huns, seeking better land and climate. This led to conflicts as Rome took advantage of the tribes.
3) The Visigoths rebelled against Rome in 378 in a key battle, showing Rome's military weakness. Other tribes then invaded and sacked Rome, marking the end of the Western Roman Empire.
