Which major event in 410 CE demonstrated the vulnerability of the Western Empire?

• A. The Battle of Adrianople
• B. The Crisis of the Third Century
• C. The Sack of Rome by the Visigoths led by Alaric
• D. The Fall of Carthage

Answer: (C)

The main idea being tested is how the Western Empire’s grip on power could falter when even its capital could be attacked and seized. In 410 CE, the Visigoths led by Alaric sacked Rome, a shocking event because Rome had long stood as the emblem of imperial authority and resilience. This breach showed that Rome’s defenses were no longer capable of protecting the heart of the empire, signaling a broader vulnerability in military strength, political cohesion, and economic resources in the West. It revealed how dependent the empire had become on precarious arrangements with barbarian groups and on stretched, overextended frontiers—so when pressure mounted, even the capital could fall. The sack didn’t spell immediate collapse, but it marked a turning point in Western prestige and legitimacy, making the fragility of imperial power visible to friend and foe alike. By contrast, the other events point to different aspects or earlier moments of weakness (frontier defeats and internal decay or distant conflicts), so the sack of Rome is the clearest, most vivid demonstration of vulnerability in 410 CE.
