Who had the power of the state rome?

In ancient Rome, the power of the state was primarily held by the Senate, particularly during the Republic era, where it acted as a governing body composed of Rome's elite. However, during the transition to the Empire, power shifted to the emperors, who held supreme authority and controlled the military, administration, and legislation. Notable emperors like Augustus established the framework for imperial rule, effectively centralizing power in the hands of one individual while maintaining the facade of republican governance.
