I focus on why the competition for power among senatorial, imperial, and military elites that had stimulated the recovery of the city of Rome in the face of multiple civic and military crises no longer was effective in the later sixth and early seventh centuries. The end of Rome’s political senatorial aristocracy and its political body, the Senate, is the final “fall” of Rome. In its place, a papal-focused city dependent on Byzantine military might would emerge in the seventh century.
