Which Western Roman Emperor was ruling when Rome was sacked by Alaric in 410 AD? (r. 393-423 AD)

The story behind the answer

Honorius is correct: he was Western Roman Emperor from 393 to 423 AD when Alaric’s Visigoths sacked Rome in 410—its first fall to a foreign enemy in nearly 800 years. Honorius ruled from the safer, marsh-guarded city of Ravenna, highlighting the West’s growing vulnerability after his capable general Stilicho was executed in 408. Theodosius II was the Eastern emperor, Valentinian III ruled later (425–455), and Petronius Maximus presided over the 455 sack.

Remember it this way: “Honor” left Rome under Honorius. The 410 sack didn’t end the empire, but it shocked the Roman world, symbolizing the West’s decline and spurring figures like Augustine to reflect on the fate of earthly cities versus the City of God.
