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.
Illyricum (Roman province)
After his campaigns in Illyricum, Octavian fought a war against Marc Antony and Cleopatra VII of Egypt in 31/30 BC. He won and became the sole ruler of Rome. After that he spent a few years laying the foundations for his personal rule. Illyricum became a province as a formal administrative unit in 27 BC, with the first settlement with the Roman senate. This formalised his personal rule. The senate bestowed of the honorary title of Augustus on him. He became the first Roman emperor. Historians use the name Augustus for this period. The settlement also divided the provinces of the empire into senatorial and imperial provinces. The former were under the authority of the senate, which chose their governors form among the senators. The latter were under Augustus, who appointed their governors. Augustus held the frontier provinces, which hosted the bulk of the Roman troops. Initially Illyricum was a senatorial propreatorial province. Rebellions in the province showed the necessity of maintaining a strong force there and in 11 BC it became an imperial province under the governorship of Publius Cornelius Dolabella.
