What did Augustus become Roman Emperor?
Augustus
During the second settlement, Augustus was also granted the power of a tribune (tribunicia potestas) for life, though not the official title of tribune.[144] For some years, Augustus had been awarded tribunicia sacrosanctitas, the immunity given to a Tribune of the Plebs. Now he decided to assume the full powers of the magistracy, renewed annually, in perpetuity. Legally, it was closed to patricians, a status that Augustus had acquired some years earlier when adopted by Julius Caesar.[143]
