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.
Fasti Capitolini
The Fasti Capitolini, or Capitoline Fasti, are a list of the chief magistrates of the Roman Republic, extending from the early fifth century BC down to the reign of Augustus, the first Roman emperor. Together with similar lists found at Rome and elsewhere, they form part of a chronology referred to as the "Fasti Annales", "Fasti Consulares", or "Consular Fasti", or occasionally just the "fasti".
