Ptolemy XI Alexander II in Wikipedia
Ptolemy XI Alexander II (Πτολεμαῖος Ἀλέξανδρος, Ptolemaĩos Aléxandros) was a member of the Ptolemaic
dynasty who ruled Egypt for a few days in 80 BC.
Ptolemy XI was born to Ptolemy X Alexander and either Cleopatra Selene or Berenice III. Ptolemy IX
Lathryos died in 81 BC or 80 BC, leaving no legitimate heir, and so Cleopatra Berenice (another name of
Berenice III) ruled alone for a time. However, Rome's Sulla wanted a pro-Roman ruler on the throne, and
sent the young son of Ptolemy X to Egypt, displaying Ptolemy Alexander's will in Rome as justification for
this obvious intervention.
The will also required Ptolemy XI to marry Cleopatra Berenice, who was his stepmother and half-sister (or
possibly his natural mother - the ancient sources are unclear). However, nineteen days after the marriage,
Ptolemy murdered his bride for unknown reasons, an unwise move since Berenice was very popular; Ptolemy
was immediately lynched by the citizens of Alexandria.
He was succeeded by Ptolemy XII.
