The western empire experienced repeated succession crises and civil wars that consumed resources and weakened political authority. Emperors increasingly depended on military powerbrokers whose interests did not always align with central government.
Tax revenues and military recruitment became harder to sustain as provinces were lost. Groups conventionally called 'barbarians' were not a single external force; many served within Roman armies or negotiated settlement inside imperial territory.
The deposition of Romulus Augustulus in 476 is a useful conventional date, not a moment when Roman life abruptly ended. Institutions, identities and law continued in transformed forms.
