Philip II of Macedon

King of Macedon — who transformed Macedon from a peripheral semi-barbaric kingdom into the dominant power in Greece — inventor of the Macedonian phalanx (sarissa pike formation), the combined arms system — and father of Alexander the Great, who inherited his military machine.

Creates the military system that Alexander inherited and used to conquer the world — Philip's sarissa phalanx (4–6 meter pikes that outreached any existing Greek weapon), combined with companion cavalry, created a combined arms system that defeated every Greek polis army and provided Alexander the tool for his conquests.
