Answer:
Romans' lives collapsed. Since 509 B.C., Rome has been famous for its cooperative and participatory government system that combined executive magistrates with an aristocratic Senate and democratic assemblies. For centuries, the republic persisted, and no single man ever seized power. But within 100 years of Rome's imperial victories in 146, the republican system would be dead. The triumph of the Roman Republic was simultaneously the beginning of the end of the Roman Republic.
