How did Augustus transform Rome from republic to empire?

Following his victory over Mark Antony, Augustus enacted legal and political reforms between 30 BC and 2 BC that transitioned Rome from a republic into an autocracy. He maintained absolute control through command of the military while preserving the outward appearance of republican governance centered around the Senate. His authority rested legally on combined proconsular imperium over the provinces and tribunician powers over civil government.

What we know

• Augustus's constitutional power was primarily based on proconsular imperium over the army and provinces combined with tribunician authority over civil government. [4, 5]
• The period of constitutional reform ended in 2 BC when the Roman Senate granted Augustus the title Pater Patriae. [2]
• Although the Emperor and the Senate were theoretically co-equal branches of government, the Senate functioned in practice as a vehicle for imperial autocratic power. [3, 4, 5]
• Traditional republican magistracies like the consulship, praetorship, and quaestorship were preserved under the imperial system. [4]

Still open

• Historical sources report persistent rumors that Augustus was poisoned by his wife Livia rather than dying of natural causes.
