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.

With Antony dead, and Lepidus marginalised, the second triumvirate was effectively dissolved, leaving Octavian as the sole power. Thus the republic came to and end. Octavian's powers progressively increased, he was granted the title "Augustus" by the Senate and adopted the title "princeps senatus" in 27 BC although technically a consul, and shortly after "Imperator" in effect Emperor and the first phase of the Roman Empire, the Principate (27 BC – 284 AD) was born. In exchange for this redistribution of powers, a long history of civil wars came to an end, replaced by the Augustan age (27 BC – 14 AD).
