After the demise of the Second Triumvirate, Augustus restored the outward façade of the free Republic, with governmental power vested in the Roman Senate, the executive magistrates, and the legislative assemblies, yet maintained autocratic authority by having the Senate grant him lifetime tenure as supreme military command, tribune, and censor. A similar ambiguity is seen in his chosen names, the implied rejection of monarchical titles whereby he called himself "Princeps Civitatis" ("First Citizen") juxtaposed with his adoption of the ancient title Augustus.
