Bithynia, Kingdom of

Near East (333–190 BCE): Hellenistic Conquests and Cultural Transformations

Alexander's Empire and its Immediate Aftermath (333–322 BCE)

The year 333 BCE inaugurates the Hellenistic Age when Alexander III of Macedon defeats the Persian Empire, transforming the geopolitical landscape of the Near East. Alexander’s swift military successes culminate in notable victories at the battles of Granicus (334 BCE), Issus (333 BCE), and Gaugamela (331 BCE). After the prolonged and pivotal siege of Tyre in 332 BCE, Alexander's domain stretches from Greece to the borders of India. He strategically integrates conquered territories through city foundations, notably Alexandria in Egypt, and religious accommodations, earning acceptance among local populations. His unexpected death in 323 BCE at Babylon triggers a complex power struggle among his generals—Perdiccas, Ptolemy Soter, Seleucus, and Antigonus Monophthalmus—eventually leading to the division of Alexander’s vast empire into separate dynasties.

Emergence of the Hellenistic Monarchies (321–298 BCE)

Alexander's territories fragment into significant Macedonian dynasties by 298 BCE. In Egypt, the Ptolemies establish a prosperous rule, significantly influencing the region by founding the renowned Library of Alexandria and the monumental Pharos Lighthouse. In Syria and Mesopotamia, the Seleucid dynasty emerges, though it remains in recurrent conflict with the Ptolemies, particularly over strategically vital areas such as Coele-Syria (modern-day Lebanon and southern Syria). Notably, after a forty-year conflict, a decisive Seleucid victory concludes initial hostilities over Phoenician territories.

Cultural Integration and Scholarly Achievement (297–274 BCE)

The Near East experiences widespread Hellenization, adopting Greek artistic, scientific, and architectural standards. Intellectual advancement peaks with scholars like Euclid, whose foundational texts on geometry and optics profoundly influence science. Cities such as Ashkelon and Ashdod are widely recognized by their Hellenized names, Ascalon and Azotus, exemplifying the era’s cultural synthesis. Egypt’s Ptolemaic Museum and Library at Alexandria become major scholarly hubs, further embedding Greek culture and intellectualism into the region.

Dynastic Rivalries and Egyptian Decline (273–226 BCE)

The Near East remains marked by fierce dynastic rivalries, particularly the Damascene War (280 BCE) and the subsequent First Syrian War (274 BCE). The internal stability of Ptolemaic Egypt significantly weakens due to court intrigues, rebellions, and economic strains. Antiochus III exploits this turmoil, resulting in Egypt's near-total loss of its Asian territories following the Battle of Panium (200 BCE). Such territorial shifts profoundly alter regional power structures.

Revolts and the Rise of Regional Powers (225–190 BCE)

Seleucid domains experience instability due to revolts by powerful satraps, notably Achaeus and Attalus of Pergamon, who successfully assert independence in Asia Minor. Attalus I consolidates Pergamon's power through victories over the Galatians, celebrated in the renowned sculpture The Dying Gaul. The century ends with the devastating Roman–Syrian War (192–188 BCE), significantly curtailing Seleucid authority, limiting it to a fragmented domain centered in Mesopotamia and inland Syria.

Legacy of the Age

The Near East during the Hellenistic Age undergoes profound political and cultural transformations marked by the spread of Greek culture, administrative reforms, and vibrant urban planning. Influential cities like Alexandria and Pergamon symbolize these shifts, becoming enduring centers of culture and learning. Despite flourishing intellectually and artistically, persistent dynastic conflicts and internal instabilities ultimately create vulnerabilities that pave the way for Roman ascendancy, marking this period as a crucial transition shaping the historical evolution of the Near East.

…Byzantium, and …

The formidable task of holding together the empire falls to the son and successor of Seleucus on his father's assassination in 281 BCE.

Antiochus entombs his father's ashes in Seleucia, initiates (probably) the posthumous cult of his father, and orders his veneration as Zeus Nicator.

He is soon compelled to make peace with his father's murderer, Ptolemy Keraunos, apparently abandoning Macedonia and Thrace.

In Anatolia he is unable to reduce Bithynia or the Persian dynasties that rule in Cappadocia.

Antiochus is immediately beset by revolts in Syria (probably instigated by Egypt) and by independence movements in …

…northern Anatolia, whose states (led by Heraclea, …

…Bithynia, and …

…Pontus), form a league against the Seleucid king.

Pontus, with its capital at Amaseia (modern Amasya) established at the end of the fourth century in the wake of Alexander's conquests, is superficially Hellenized, but the kingdom retains its Persian social structure, with temple priests and Persianized feudal nobles ruling over a heterogeneous village population.

Bithynia, a region of northwest Anatolia ruled by a local dynasty and never much affected by Phrygian or Persian rule, adjoins the Sea of Marmara, the Bosporus, and the Black Sea, thus occupying an important and precarious position between East and West.

The district had been occupied late in the second millennium BCE by warlike tribes of Thracian origin who harried Greek settlers and Persian envoys alike.

Their remarkable pugnacity had kept them from complete Persian domination after the sixth century; in addition, they never submitted to Alexander the Great or his Seleucid successors.

The small but powerful state has evolved from tribal government to Hellenistic kingship.

Nicomedes, becoming king of Bithynia, in 278, commences his reign by putting to death two of his brothers but the third, subsequently called Zipoetes II, raises an insurrection against him and succeeds in maintaining himself, for some time, in the independent sovereignty of a considerable part of Bithynia.

Meanwhile, Nicomedes is threatened with an invasion from Antiochus, who had already made war upon his father, Zipoetes I, and, to strengthen himself against this danger, he concludes an alliance with Heraclea Pontica and shortly afterwards with Antigonus II Gonatas.

The threatened attack, however, passes over with little injury.

Antiochus actually invades Bithynia but withdraws again without risking a battle.

Nicomedes, more against his brother than his foreign enemies, now calls in the assistance of more powerful auxiliaries and enters into an alliance with the warlike Celts, or Gauls, who, under Leonnorius and Lutarius, had arrived on the opposite side of the Bosporus and are, at this time, engaged in the siege of Byzantium, 277 BCE.

Three Gallic tribes, twenty thousand strong, are initially recruited.

Having furnished them with the means of crossing into Asia, he first turns the arms of his new auxiliaries against Zipoetes II, whom he defeats and puts to death, and thus reunites the whole of Bithynia under his dominion.

Of the events that follow we have little information.

It is probable that the Celts subsequently assisted Nicomedes against Antiochus, but no particulars are recorded, either of the war or the peace that terminated it.

It appears, however, that Nicomedes was left in the undisturbed possession of Bithynia, which he continues to govern from this time until his death and which is to rise to a high degree of power and prosperity during his long and peaceful reign.

Antiochus, preoccupied with the pacification of Syria following the Gallic incursions in Greece, encourages Greek immigration to his realm and establishes many new cities in Asia Minor to serve as counterweights to the Gauls.

The Gauls, after discharging their military service to Bithynia, have by 276 settled in parts of Phrygia but continue to ravage and plunder on their own.
