Battle of the Nile (47 BC) in the context of "Arsinoe IV"

Cleopatra VII Thea Philopator (Koine Greek: Κλεοπάτρα Θεά Φιλοπάτωρ, lit. 'Cleopatra father-loving goddess'; 70/69 BC – 10 or 12 August 30 BC) was Queen of the Ptolemaic Kingdom of Egypt from 51 to 30 BC, and the last active Hellenistic pharaoh. A member of the Ptolemaic dynasty, she was a descendant of its founder Ptolemy I Soter, a Macedonian Greek general and companion of Alexander the Great. Her first language was Koine Greek, and she is the only Ptolemaic ruler known to have learned the Egyptian language, among several others. After her death, Egypt became a province of the Roman Empire, marking the end of the Hellenistic period in the Mediterranean, which had begun during the reign of Alexander (336–323 BC).

Born in Alexandria, Cleopatra was the daughter of Ptolemy XII Auletes, who named her his heir before his death in 51 BC. Cleopatra began her reign alongside her brother Ptolemy XIII, but a falling-out between them led to a civil war. Roman statesman Pompey fled to Egypt after losing the 48 BC Battle of Pharsalus against his rival Julius Caesar, the Roman dictator, in Caesar's civil war. Pompey had been a political ally of Ptolemy XII, but Ptolemy XIII had him ambushed and killed before Caesar arrived and occupied Alexandria. Caesar then attempted to reconcile the rival Ptolemaic siblings, but Ptolemy XIII's forces besieged Cleopatra and Caesar at the palace. Shortly after the siege was lifted by reinforcements, Ptolemy XIII died in the Battle of the Nile. Caesar declared Cleopatra and her brother Ptolemy XIV joint rulers, and maintained a private affair with Cleopatra which produced a son, Caesarion. Cleopatra traveled to Rome as a client queen in 46 and 44 BC, where she stayed at Caesar's villa. After Caesar's assassination, followed shortly afterwards by the sudden death of Ptolemy XIV (possibly murdered on Cleopatra's order), she named Caesarion co-ruler as Ptolemy XV.

The reign of Cleopatra VII of the Ptolemaic Kingdom of Egypt began with the death of her father, Ptolemy XII Auletes, by March 51 BC. It ended with her suicide in August 30 BC, which also marked the conclusion of the Hellenistic period and the annexation of Egypt into a Roman province. In the style of her Greek predecessors, Cleopatra reigned over Egypt and other territories as an absolute monarch, although the Roman Republic frequently interfered in its internal affairs. Her personal rule of Egypt was characterized by a continued reliance on agriculture, extensive trade and conflict with other states, the tackling of corruption, strategic management of the bureaucracy, and ambitious building projects.

Cleopatra initially acceded to the throne alongside her younger brother Ptolemy XIII, but a fallout between them led to open civil war. Further chaos ensued when the Roman consul Julius Caesar pursued his rival Pompey into Ptolemaic Egypt, a Roman client state. Upon arrival, Caesar discovered that Pompey had been assassinated on the orders of Ptolemy XIII. Caesar attempted to reconcile the siblings, but a discontent Ptolemy XIII and his adviser Potheinos raised forces against Caesar and Cleopatra. Reinforcements lifted the siege in early 47 BC, and Ptolemy XIII died shortly afterwards in the Battle of the Nile. Arsinoe IV (Cleopatra's younger sister and a rival claimant to the throne) was exiled, and Caesar, now dictator, declared Cleopatra and her younger brother Ptolemy XIV co-rulers of Egypt. However, Caesar maintained a private affair with Cleopatra that produced a son, Caesarion, before he departed Alexandria for Rome.

The siege of Alexandria was a series of skirmishes and battles occurring between the forces of Julius Caesar, Cleopatra VII, Arsinoe IV, and Ptolemy XIII, between 48 and 47 BC. During this time Caesar was engaged in a civil war against remaining Republican forces.

The siege was lifted by relief forces arriving from Syria. After a battle contesting those forces' crossing of the Nile delta, Ptolemy XIII and Arsinoe's forces were defeated.

Antipater I the Idumaean (113 or 114 BCE – 43 BCE) was the founder of the Herodian dynasty and father of Herod the Great. According to Josephus, he was the son of Antipas and had formerly held that name. A native of Idumaea (a region southeast of Judah in which the Edomites settled during the classical period) Antipater became a powerful official under the later Hasmonean kings and subsequently became a client of Roman General Pompey when Pompey conquered Judah in the name of the Roman Republic.

After Julius Caesar defeated Pompey at the Battle of Pharsalus, Antipater sided with Caesar during the Roman Civil War. During Caesar's Egyptian campaign, Antipater joined Mithridates of Pergamon's army marching to rescue Caesar in Alexandria. Caesar made him chief minister of Judea, as Judah became known to the Romans, with the right to collect taxes. Eventually Caesar made Antipater's sons Phasaelus and Herod the governors of Jerusalem and Galilee, respectively. After the assassination of Caesar, Antipater was forced to side with the Liberators against the Caesarians. The pro-Roman politics of Antipater led to his increasing unpopularity among the devout, non-Hellenised Jews. He died by poison. The diplomacy and artful politics of Antipater, as well as his insinuation into the Hasmonean court, paved the way for the rise of his son Herod the Great, who used this position to marry the Hasmonean princess Mariamne, endear himself to Rome and become king of Judea under Roman influence.
