Ancient Macedonian Army

In this episode, we explore the dramatic rise and eventual decline of the Ancient Macedonian army, tracing how Philip II transformed a fragmented local force into a highly disciplined, professional military built on innovative training and combined arms tactics, and how Alexander the Great leveraged that foundation to conquer an empire stretching to India. We break down the army’s defining features—from the fearsome sarissa-armed phalanx and elite Companion cavalry to advanced siege artillery—and examine how historians piece together these details from ancient sources and archaeology. This episode also looks at why, after Alexander’s death, the army’s increasing rigidity left it vulnerable, ultimately falling to the more flexible Roman legions.
