Angrivarii
The wars began in the last years of the reign of Augustus, first emperor of Rome. Augustus died an old but respected man in the year 14 and was celebrated with much pomp and splendor. He left a document to be read to the senate posthumously, expressly forbidding extension of the empire beyond the Rhine. News of the will was welcomed by the Germans, thinking it gave them a free hand in the region. Germanicus found it necessary to pacify the border, which he did by a combination of scorched earth raids and offers of alliance with Rome - in short, stick and carrot. These raids also kept the army of the lower Rhine distracted from the possibility of mutiny, which had broken out on Augustus's death and only been quelled by concessions and executions.
Ballot laws of the Roman Republic
After the Final War ended in 30 BC, Octavius controlled all of Rome. He concentrated the powers of consul, tribune, and pontifex maximus in his own hands, ruling as an autocrat in all but name. Octavius, renamed Augustus in 27 BC, would be the first Roman emperor. These events marked the end of the Republic and the beginning of the Principate. Although the assemblies continued to meet during the Principate, Augustus removed their judicial role and began transferring their electoral power to the Senate; his successor Tiberius would completely end the electoral role of the assemblies. The assemblies continued to have legislative powers, but even under Augustus this power was exercised more and more rarely. Rome became an autocratic state in all but name, and the ballot laws became irrelevant to the running of the state.
