Ptolemy XII Auletes
After a few months of sole rule, Berenice summoned her younger half-brother and former step-son, Ptolemy XI, from Rome to serve as co-regent. According to Appian, this co-regency was established at the behest of the Roman dictator Sulla, who hoped that Ptolemy XI would serve as a pliant client king. Ptolemy XI was crowned king on 3 April 80 BC and murdered Berenice a few days later. Bernice III death angered the Alexandrians, and in response to her murder the people rioted on 22 April 80 BC. He was cornered in the gymnasium and killed. The throne then passed to Ptolemy XII Auletes, who was an illegitimate son of Ptolemy IX and the half-brother of Berenice.
