The brief struggle over, Otho returned in triumph to the camp, and on the same day was duly invested by the senators with the name of Augustus, the tribunician power and the other dignities belonging to the principate.
The incorporation of existing towns, hitherto non-Roman, in the uniform municipal system of the principate took place mainly in the eastern part of the Empire, where Greek civilization had long fostered urban life.
At any rate by the end of the 1st century of the principate municipia are numerous in the western as well as the eastern half of the Empire, and the towns are everywhere centres of Roman influence.
The municipal constitution of the 1st century of the principate is based upon the type of government common to Greece and Rome from earliest times.
In the principate, patrician rank, a sort of abstract conception based upon the earlier state of affairs, was held to be a dignity suitable to be conferred on an individual holder of office.
