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.
Cleopatra
Cleopatra decided in her last moments to send Caesarion away to Upper Egypt, perhaps with plans to flee to Kushite Nubia, Ethiopia, or India. Caesarion, now Ptolemy XV, would reign for a mere 18 days until executed on the orders of Octavian on 29 August 30 BC, after returning to Alexandria under the false pretense that Octavian would allow him to be king. Octavian was convinced by the advice of the philosopher Arius Didymus that there was room for only one Caesar in the world. With the fall of the Ptolemaic Kingdom, the Roman province of Egypt was established, marking the end of the Hellenistic period. In January 27 BC Octavian was renamed Augustus ("the revered") and amassed constitutional powers that established him as the first Roman emperor, inaugurating the Principate era of the Roman Empire.
