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.
History of Europe
The Romans expanded from Arabia to Britannia. In 44 BC as it approached its height, its dictator Julius Caesar was murdered by senators in an attempt to restore the Republic. In the ensuing turmoil, Octavian (ruled as Augustus; and as "divi filius", or Son of God, as Julius had adopted him as an heir) usurped the reins of power and fought the Roman Senate. While proclaiming the rebirth of the Republic, he had ushered in the transfer of the Roman state from a republic to an empire, the Roman Empire, which lasted for more than four centuries until the fall of the Western Roman Empire.
