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.
Georgics
Beginning with Caesar's assassination in 44 BC and ending with Octavian's victory over Anthony and Cleopatra at Actium in 31 BC, Rome had been engaged in a series of almost constant civil wars. After almost 15 years of political and social upheaval, Octavian, the sole surviving member of the Second Triumvirate, became firmly established as the new leader of the Roman world. Under Octavian, Rome enjoyed a long period of relative peace and prosperity. However, Octavian's victory at Actium also sounded the death knell of the Republic. With Octavian as the sole ruler of the Roman world, the Roman Empire was born.
