Honorius ruled the Western Empire for the entirety of his reign from Ravenna after 402, having abandoned Milan when Alaric's forces pushed deep into northern Italy. His court's removal to that defensible marsh city did nothing to stop the sack of Rome in 410 — an event that shook the Roman world far more psychologically than militarily. That this issue was struck at Cyzicus, deep in what was effectively Eastern imperial territory under Arcadius and then Theodosius II, reflects the administrative entanglement of the divided empire during Honorius's increasingly nominal western authority.
