I was actually thinking of doing a Guess the PoD map for my next NES, but then I decided that while being able to suddenly conjure up one of them would be preferable, I can’t, and so I would find it more interesting, and perhaps even easier, to just write the timeline out in full. So, here we go, starting with a somewhat short instalment. I am not completely convinced by the likelihood of all of it, but I am sure people will tell me (please) where there are faults.
268 BC to 235/4 BC
The Chremonidean War of 268 BC was, perhaps, a turning point in our timeline, in which it is the last of a series of failed southern Greek rebellions against the Macedonian garrisons that had been placed in many of the Greek poleis. However, in this timeline, it is a turning point of another sort entirely, and one that marked the rise of an Empire.
Macedonia’s monarchy was an insecure one. Its ruler had been but one of many pretenders to the Macedonian throne, and the dynasty of Lysimachus had been its ruling house for many years before the succession of the Antigonus Gonatas to the throne, which he had reinforced by being the first of these pretenders to defeat the invading Celts conclusively at Lysimachia.
Sparta, under Areus I, had gained notable power in the Peloponnese, and he had won a great amount of glory in expelling Pyrrhus from Lacedaemon in 272, and he also had rebuilt much of the former Peloponnesian League, and made connections in Crete with the city of Gortys.
Athens declared war against Macedonia, in the name of freedom, and quickly expelled the garrison that was keeping the port for the Macedonian King, and the Macedonians marched south to prevent their Peloponnesian allies from joining up with them. However, Ptolemy Philadelphus, hoping to assert his own hegemony in southern Greece in the place of the Macedonian hegemony, landed a considerable expeditionary force in 266 in the Argolid, and, marching to join Areus, they forced the passage of the Isthmus, breaking Antigonus’s army in the process. Antigonus withdrew, and Ptolemy was able to install garrisons in the Acrocorinth, and captured much of the Antigonid fleet by taking it by surprise off Paros. Euboea quickly fell to Philadelphus’s fleet, and Athens and Sparta made their peace with Antigonus; the rebirth of the Peloponnesian League was assured, and hegemony in southern Greece fell, for the moment, to Egypt.
Ptolemy was quick to land his forces at Lysimachia to capitalise on his victory, and when the Macedonian army was smashed at Derdia by Alexander II of Epirus, he marched west to install one of the pretenders, Ptolemy II (son of Lysimachus), at Pydna, leaving Upper Macedonia under Epirot control, before marching to secure the last of the renowned fetters of Greece, Demetrias. Having, predictably, renamed it Ptolemais, he withdrew, leaving garrisons around the Aegean perimeter.
Alexander, heady with victory and acclaimed by his troops as true to his namesake, and with his position enormously strengthened by the possession of much of Macedonia, boarded ship with a large army, complete with elephants, to succeed where his father had failed; the holy grail of Italian supremacy was to be a defining feature of the Epirot monarchy for many of Pyrrhus’s descendants. He launched the Alexandrine War in 245, and added to the mess that was the Mediterranean at the time. For, of course, Rome and Carthage were engaged at the time in war over Sicily.
Alexander landed at Taras, and it rose in support of him, and his large army posed a clear threat to Rome’s security. The Romans were forced to withdraw forces from Sicily to deal with the Epirot threat, and this turned the fortunes of the Carthaginians on the island, who, within two years, had Messana under siege, and Alexander had defeated the Romans in several engagements. Rome could do little but concede Messana to the Carthaginians and withdraw, and Roman forces defeated Alexander at Caulonia, smashing his army, which was hardly able to deal with both consuls’ armies at once. Taras expelled his garrison before he could reach it, and he barely escaped back to Epirus with the remainder of his army, only for it to be smashed again by the army of Ptolemy, the king of Macedonia, in 241.
The two sons of Alexander, called Pyrrhus and Ptolemy, escaped back to Taras, and succeeded in rousing the mob to rebellion again against Rome. An army was collected together, with Lucanian and Messapian elements as well as Greek ones. Pyrrhus concluded an alliance with Carthage, which quickly despatched an army, which landed at Thurii and marched directly towards Rome.
Meanwhile, though, events were complicated by Ptolemy of Macedonia’s death in 240. The Epirot aristocracy rebelled, with the support of the rising Aetolian League, and placed Pyrrhus back on the throne, and so, leaving his brother Ptolemy in charge of events in Taras, he sailed back home to take control, just in time to get control of Epirus before Lysimachus, Ptolemy’s son, could strike back. The two kings fought a bitter war for seven years with no result in sight. The Tarentine mob, furious at their apparent betrayal, set upon and killed Ptolemy in the marketplace, and pledged allegiance to Carthage.
The Romans were shortly defeated in a series of battles over the next five years, and Carthage, at the time, had no real desire to secure control over more than the Greek poleis of southern Italy. The Samnites revolted and the Boii and Insubres invaded, and, fearing a general revolt of all its allies, and, as always, with something of an irrational fear of the Gauls, Rome gave Carthage control of Magna Graecia and paid a large indemnity in 234. Having to shoulder a huge indemnity merely caused even more revolts, and Rome was now faced with the fearsome opposition of the Samnites, many of its other socii, and the Gauls all at once.
Meanwhile, one triumph led to another for the Ptolemies; the Second Syrian War was a complete victory, and ensured Ptolemaic control over the coast of Asia Minor, and the Third Syrian War saw the Seleucid armies defeated, and, with undisputed naval supremacy, the Ptolemies emerged from the war with control of Syria in 240. The Seleucids removed their court to Seleucia on the Tigris, and Antiochus Hierax secured firm control of Asia Minor, and, without any interference from the Seleucid monarch at Babylon, firmly secured Pergamum under his rule, and allied himself with the Galatians. He used them to eject Ariarathes from Cappadocia, enlarging the area under Galatian control considerably, and his wars with Ariarathes took up Hierax’s military efforts, as well as those of the Galatians, for the next decade. Hierax also allied himself with Bithynia by marriage.
Nevertheless, the Ptolemaic kingdom now had to guard Syria against both Callinicus and Hierax, and this meant that, despite concluding peace with both rulers, Euergetes was not able to intervene effectively in Greece, when, with his land reform smoothly carried out with the support of the other members of the Peloponnesian League, Cleomenes III of Sparta seized the dual opportunity of Egypt’s distraction in Mesopotamia and the inconclusive war between Pyrrhus and Lysimachus in the north, and besieged Corinth in 236, with a large army. It fell to his forces the following year, and it seemed, now, as if all central Greece lay prone before him.
