Macedonian alliances against Dardania Since it was difficult to defeat the Dardanians militarily,
Philip V drew up a plan to get the large
Germanic/
Celtic tribe of the Bastarnae against them. While on campaign in
Thrace in 184 BC Philip sent agents to stir up the barbarians along the river
Danube, that they might invade
Italy. Two years later Philip was pleased to learn that the Bastarnae had accepted his alliance and were offering a princess in marriage for one of his sons,
Perseus as it turned out. This formidable people, dwelt beyond the lower Danube but were often willing to join in expeditions far from their homelands. The following year Philip mass deportations from
Paeonia where he filled the towns with
Thracians and other barbarians, as being likely to remain more securely loyal to him in the coming hour of danger, that is war with
Rome. In fact Philip's purpose for the Bastarnae was more specific to the security of Macedonia: They were to invade and eject the Dardanians under Monunius and take over their country, and later continue on their way through
Illyria, finally reaching Italy.
Livy (XL, 574-9) writes that Philip's purpose was to wipe out the Dardanians and settle the Bastarnae in their lands (in the
Polog valley), and send them to Italy and lay it waste, leaving their women and children in Dardania. It was a typically ruthless yet realistic scheme, and was later imitated in the Danube lands on more than one occasion by the
Romans. The Bastarnae were accompanied by the kindred
Scordisci whose lands their route lay. To get the Bastarnae to Monunius' State, Philip had gone to great trouble and expense to arrange safe passage through the Thracians. They left home after a great deal of hesitation but had gone as far as
Amphipolis when, in summer of
179 BC, news arrived that Philip V was dead. Soon there was trouble with the Thracians and the Bastarnae retreated to Donica (perhaps
Rila), a high mountain in western Thrace. After Philp's death, his son Perseus tried to follow through his fathers plans. After further skirmishes some decided to return home and set off for
Appolonia and Mesembria on the
Black Sea coast of Thrace, but the rest, under the leadership of Clondicus, pressed on towards Monunius and set about to eject the population in accordance with their arrangement with the late king.
Rome's refusal of help In 176 BC Monunius sent envoys to Rome with news of an invasion by the Bastarnae. The Dardanian envoys declared that they were warriors massive in size and numbers and alleged that they were in league with Perseus and the Gauls. Representatives from
Thessaly appeared also in order to confirm the story and back up Monunius. The patres would make their customary response, they would send an embassy to investigate. On the return of that embassy, Livy records that the Romans reported only that a Dardanian war was underway, and
Appian adds that they had observed a major military build-up in Macedonia. Perseus in the meantime, dispatched his own envoys to Rome with denials that he had any part in the activity of the Bastarnae. The senate would neither censure nor absolve Perseus, but simply directed that he take care to giving the appearance of observing his treaty with Rome and therefore the senate did nothing to support Monunius. ==Bastarnae invasion==
