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 accounting
By the time of Emperor Augustus (63 BC - AD 14), the Roman government had access to detailed financial information as evidenced by the "Res Gestae Divi Augusti" (Latin: "The Deeds of the Divine Augustus"). The inscription was an account to the Roman people of the Emperor Augustus' stewardship, and listed and quantified his public expenditure, including distributions to the people, grants of land or money to army veterans, subsidies to the "aerarium" (treasury), building of temples, religious offerings, and expenditures on theatrical shows and gladiatorial games, covering a period of about forty years. The scope of the accounting information at the emperor's disposal suggests that its purpose encompassed planning and decision-making.
