Final answer:
The fall of Rome was precipitated by external conflicts with Germanic tribes, Persian Empire, and internal division and political instability within the Roman Empire.
Step-by-step explanation:
The external conflict that led to the fall of Rome was the invasion and attacks from the Germanic tribes, particularly the Visigoths led by Alaric and the Vandals led by Genseric. These barbarian invasions weakened the Roman Empire and ultimately contributed to its collapse. The Visigoths sacked Rome in 410 AD, while the Vandals captured and pillaged the city in 455 AD. These events marked significant turning points in the decline of the Roman Empire.
Another external conflict that played a role in the fall of Rome was the ongoing tension with the Persian Empire. The Romans and Persians engaged in several wars, depleting their resources and weakening their respective empires. The constant state of conflict put a strain on the already struggling Roman Empire.
Lastly, the internal division and political instability within the Roman Empire also contributed to its downfall. The empire faced political and military instability, economic decline, and social unrest, which made it vulnerable to external attacks.
