Cyrenaica (246 BC) , the wife and half-cousin of Ptolemy III
Cyrene had been the first Ptolemaic territory outside Egypt, but Magas had rebelled against Ptolemy II and declared himself king of
Cyrenaica in 276 BC. The aforementioned engagement of Ptolemy III to Berenice had been intended to lead to the reunification of Egypt and Cyrene after Magas' death. However, when Magas died in 250 BC, Berenice's mother Apame refused to honour the agreement and invited an Antigonid prince,
Demetrius the Fair, to Cyrene to marry Berenice instead. With Apame's help, Demetrius seized control of the city, but he was assassinated by Berenice. A republican government, led by two Cyrenaeans named Ecdelus and Demophanes, controlled Cyrene for four years. It was only with Ptolemy III's accession in 246 BC, that the wedding of Ptolemy III and Berenice seems to have actually taken place. Ptolemaic authority over Cyrene was forcefully reasserted. Two new port cities were established, named
Ptolemais and Berenice (modern
Tolmeita and
Benghazi) after the dynastic couple. The cities of Cyrenaica were unified in a League overseen by the king, as a way of balancing the cities' desire for political autonomy against the Ptolemaic desire for control.
Third Syrian War (246–241 BC) In July 246 BC,
Antiochus II, king of the
Seleucid empire, died suddenly. By his first wife
Laodice I, Antiochus II had had a son,
Seleucus II, who was about 19 years old in 246 BC. However, in 253 BC, he had agreed to repudiate Laodice and marry Ptolemy III's sister
Berenice. Antiochus II and Berenice had a son named Antiochus, who was still an infant when his father died. A succession dispute broke out immediately after Antiochus II's death. Ptolemy III quickly invaded Syria in support of his sister and her son, marking the beginning of the Third Syrian War (also known as the Laodicean War). An account of the initial phase of this war, written by Ptolemy III himself, is preserved on the
Gurob papyrus. At the outbreak of war, Laodice I and Seleucus II were based in western
Asia Minor, while the widowed Queen Berenice was in
Antioch. The latter quickly seized control of
Cilicia to prevent Laodice I from entering Syria. Meanwhile, Ptolemy III marched along the Levantine coast encountering minimal resistance. The cities of
Seleucia and Antioch surrendered to him without a fight in late autumn. At Antioch, Ptolemy III went to the royal palace to plan his next moves with Berenice in person, only to discover that she and her young son had been murdered. In light of this success, he may have been crowned 'Great King' of Asia. Early in 245 BC, he established a governor of the land 'on the other side' of the
Euphrates, indicating an intention to permanently incorporate the region into the Ptolemaic kingdom. At this point however, Ptolemy III received notice that a revolt had broken out in Egypt and he was forced to return home to suppress it. By July 245 BC, the Seleucids had recaptured Mesopotamia. The Egyptian revolt is significant as the first of a series of native Egyptian uprisings which would trouble Egypt for the next century. One reason for this revolt was the heavy tax-burdens placed on the people of Egypt by Ptolemy III's war in Syria. Furthermore, papyri records indicate that the
inundation of the
Nile river failed in 245 BC, resulting in famine. After his return to Egypt and suppression of the revolt, Ptolemy III made an effort to present himself as a victorious king in both Egyptian and Greek cultural contexts. Official propaganda, like
OGIS 54, an inscription set up in
Adulis and probably the copy of an inscription in Alexandria, vastly exaggerated Ptolemy III's conquests, claiming even
Bactria among his conquests. At the new year in 243 BC, Ptolemy III incorporated himself and his wife Berenice II into the Ptolemaic state cult, to be worshipped as the
Theoi Euergetai (Benefactor Gods), in honour of his restoration to Egypt of statues found in the Seleucid territories, which had been seized by the
Persians. captured
Ephesus from the Seleucids in 246 BC. At an uncertain date around 245 BC, he fought a
sea-battle at Andros against King
Antigonus II of
Macedon, in which the Ptolemaic forces were defeated. It appears that he then led an invasion of Thrace, where
Maroneia and
Aenus were under Ptolemaic control as of 243 BC. Ptolemy Andromachou was subsequently assassinated at Ephesus by Thracian soldiers under his control. The only further action known from the war is some fighting near
Damascus in 242 BC. Shortly after this, in 241 BC, Ptolemy made peace with the Seleucids, retaining all the conquered territory in Asia Minor and northern Syria. Nearly the whole Mediterranean coast from Maroneia in
Thrace to the
Syrtis in
Libya was now under Ptolemaic control. One of the most significant acquisitions was Seleucia Pieria, the port of Antioch, whose loss was a significant economic and logistical set-back for the Seleucids.
Later reign (241–222 BC) The conclusion of the Third Syrian War marked the end of military intervention in the Seleucid territories, but Ptolemy III continued to offer covert financial assistance to the opponents of Seleucus II. From 241 BC, this included
Antiochus Hierax, the younger brother of Seleucus II, who rebelled against his brother and established his own separate kingdom in Asia Minor. Ptolemy III sent military forces to support him only when a group of
Galatian mercenaries rebelled against him but is likely to have supported him more tacitly throughout his conflict with Seleucus II. He offered similar support to
Attalus I, the dynast of
Pergamum, who took advantage of this civil conflict to expand his territories in northwestern Asia Minor. When the Seleucid general
Achaeus was sent in 223 BC to reconquer the territories in Asia Minor that had been lost to Attalus, Ptolemy III sent his son
Magas with a military force to aid Attalus, but he was unable to prevent Attalus' defeat. Ptolemy III maintained his father's hostile policy to
Macedonia. This probably involved direct conflict with Antigonus II during the Third Syrian War, but after the defeat at Andros in c. 245 BC, Ptolemy III seems to have returned to the policy of indirect opposition, financing enemies of the Antigonids in mainland Greece. The most prominent of these was the
Achaean League, a federation of Greek city-states in the
Peloponnese that were united by their opposition to Macedon. From 243 BC, Ptolemy III was the nominal leader (
hegemon) and military commander of the League and supplied them with a yearly payment. After 240 BC, Ptolemy also forged an alliance with the
Aetolian League in northwest Greece. From 238 to 234 BC, the two leagues waged the
Demetrian War against Macedon with Ptolemaic financial support. However, in 229 BC, the
Cleomenean War (229–222 BC) broke out between the Achaean League and
Cleomenes III of
Sparta. As a result, in 226 BC,
Aratos of Sicyon the leader of the Achaean League forged an alliance with the Macedonian king
Antigonus III. Ptolemy III responded by immediately breaking off relations with the Achaean League and redirecting his financial support to Sparta. Most of the rest of the Greek states were brought under the Macedonian umbrella in 224 BC when Antigonus revived the
Hellenic League of
Philip II of Macedon under the name of the "League of Leagues". However Aetolia and Athens remained hostile to Macedon and redoubled their allegiance to Ptolemy III. In Athens, in 224 BC, extensive honours were granted to Ptolemy III to entrench their alliance with him, including the creation of a new
tribe named
Ptolemais in his honour and a new
deme named
Berenicidae in honour of Queen Berenice II. The Athenians instituted a state religious cult in which Ptolemy III and Berenice II were worshipped as gods, including a festival, the Ptolemaia. The centre of the cult was the Ptolemaion, which also served as the
gymnasium where young male citizens undertook civic and military training. Cleomenes III suffered serious defeats in 223 BC and Ptolemy III abandoned his support for him in the next year – probably as a result of an agreement with Antigonus. The Egyptian king seems to have been unwilling to commit actual troops to Greece, particularly as the threat of renewed war with the Seleucids was looming. Cleomenes III was defeated and forced to flee to Alexandria, where Ptolemy III offered him hospitality and promised to help restore him to power. However, these promises were not fulfilled, and the Cleomenian War would in fact be the last time that the Ptolemies intervened in mainland Greece. He was succeeded by his son
Ptolemy IV without incident. ==Regime==
