*The weakness of his system.* Yet it must be admitted that this system contained two innate weaknesses. Firstly, it was built up around the personality of Augustus, who could trust himself not to abuse his great power, and secondly, the princeps, as commander-in-chief of the Roman army, was immeasurably more powerful than the second partner in the administration, the Senate, and able to assert his will against all opposition. Now, as has well been observed, the working of the principate depended upon the coöperation of the Senate and the self-restraint of the emperors, consequently, when the former proved incapable and the latter abused their power, the inevitable consequence was an autocracy. That Augustus realized this himself towards the end of his life is highly probable, yet as the one who brought order out of chaos and gave peace to an exhausted world his name will always be one of the greatest in the history of Rome or indeed of the human race. CHAPTER XVII THE JULIO-CLAUDIAN LINE AND THE FLAVIANS: 14–96 A. D. I. TIBERIUS, 14–37 A. D. *Tiberius princeps.* At the death of Augustus, Tiberius by right of his _imperium_ assumed command of the army and through his tribunician authority convoked the Senate to pay the last honors to Augustus and decide upon his successor. Like Julius Caesar, Augustus was deified, and a priestly college of Augustales, chosen from the senatorial order was founded to maintain his worship in Rome. In accordance with a wish expressed in his will, his widow Livia was honored with the name Augusta. Tiberius received the title of Augustus and the other honors and powers which his predecessor had made the prerogatives of the princeps. His _imperium_, however, was conferred for life, and not for a limited period. The ease of his succession shows how solidly the principate was established at the death of its founder.
