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.
Julius Nepos
The reasons for Orestes' decision to crown his son as a puppet-emperor, rather than become emperor himself, are somewhat unclear. However, Romulus' position was not constitutional inasmuch as he had not been recognised by the Emperor at Constantinople, in whose eyes Nepos was still the sole Augustus of the West. Romulus' short reign ended on September 4, 476, when Odoacer, head of the Germanic Foederati in Italy, captured Ravenna, killed Orestes, and deposed Romulus. Odoacer sent Romulus Augustulus to Campania in exile or retirement, after which he disappears from the historical record.
