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.
Archelaus of Cappadocia
When Octavian became the first Roman Emperor Augustus, Archelaus became an important client monarch to Rome, and Augustus considered Archelaus loyal. Augustus had no commitment to provincialization as a matter of policy. In 25 BC, Augustus assigned Archelaus to rule Cilicia Trachea, the harbor city of Elaiussa Sebaste, as well as parts of the surrounding Cilician coast and Armenia Minor. By giving Archelaus all these extra territories to govern, Augustus was able to eliminate piracy and build a more solid bulwark against Parthia.
