In OTL the Western Roman Empire officially ceased to exist when the last Emperor Romulus Agustulus was forced to abdicate in 476 AD by the Germanic General Odoacer.
Is it possible that the Western Empire could have endured past this date? After all the Eastern Roman Empire (AKA. The Byzantine Empire) lasted until 1453 AD.
Between the splitting of the Roman Empire into eastern and western halves by Diolcetian in 293 AD, up until Romulus Agustulus' abdication in 476 AD, is there a POD that would allow the Western Empire to endure for longer than it did in OTL?
