Rise of Makedon

It is 359 BC. Macedonia, in northern Greece, is teetering on the brink of collapse.
It possesses no centralised government, only a weak conscript army, no economy, no unity, and has been victim to invasions and dynastic interference from both neighbouring tribes and Greek states further afield.
The chaos has been further intensified by the sudden death of its King, Perdiccas III, slain in a battle defending his kingdom against the Illyrians - led by their King, Bardylis. Four thousand Macedonian soldiers have perished in this disaster, and now, along with their King, lay staining the ground with their blood in Northern Macedon.
Meanwhile, the victorious Bardylis and his Illyrian army prepare to push deeper into Macedon. In addition to this, down from the upper Axius valley, a Paeonian army led by Agis, probably spurred on by Macedonia’s precarious position - prepares to invade Lower Macedon.
Worse than this, pretenders to the throne have surfaced. Athens has backed a certain Argaeus. Athenian troops under him and some mercenary troops under Mantias have landed at Methone by way of an Athenian fleet!
Berisades of Thrace has also backed a pretender, this time named Pausanias, he and a Thracian force march down from the North East, preparing to march directly on Pella!
Amidst this chaos, the infant son of Perdiccas III, Amyntas IV, has been proclaimed King. His uncle Philip will tutor the boy, and act as regent of the kingdom until Amyntas is old enough to assumes the reins of power himself.
You, as the young regent Philip II, now find yourself at the centre of this turmoil. Will you be able to save your Macedon in its hour of need? Will you bring about the kind of unification, stimulation of the economy and military reforms it so desperately needs? How will you deal with the encroachments of others on your fledgling kingdom?
This is a time of diplomacy, deceit, and crushing military force. This is Total War…
