Macedonian phalanx

A dense infantry formation used by Macedonian armies, whose soldiers fought with long two-handed sarissas. It combined deep ranks and projecting spearpoints with mobile cavalry and lighter troops.

Sarissa: A long pike used by Macedonian infantry, typically wielded with both hands. Its exceptional length let several ranks project spearpoints beyond the front line.
Philip II of Macedon: King of Macedon from 359 to 336 BCE who expanded and reorganized the kingdom's military power. His reforms established the army in which the sarissa phalanx became central.
Battle of Issus: A 333 BCE battle in which Alexander the Great defeated the Persian king Darius III in southern Anatolia. The narrow battlefield constrained the phalanx while Alexander's cavalry attack decided the battle.
Roman legion: The principal organized military unit of ancient Rome, whose infantry fought in flexible subunits called maniples or cohorts. Roman units could maneuver through gaps and uneven ground that hindered a continuous pike line.
Diadochi: The generals and successors who fought over Alexander the Great's empire after his death in 323 BCE. Their kingdoms preserved the Macedonian phalanx as a central instrument of royal warfare.
Pezhetairoi: The foot companions who formed the core heavy infantry of the Macedonian army. They supplied the trained ranks that carried the sarissa formation.
Ancient Macedon: An ancient kingdom north of mainland Greece that became a major power under Philip II and Alexander the Great. The phalanx was a product of Macedon's military institutions and resources.
Battle of Gaugamela: A 331 BCE battle in which Alexander defeated Darius III near present-day Mosul, ending Achaemenid power. The phalanx held the center as cavalry maneuvers opened a path toward Darius.
Hellenistic armies: The military forces of successor kingdoms formed after Alexander the Great's empire fragmented. Successor armies inherited and adapted Macedonian pike warfare beyond the original kingdom.
Antigonid Macedon: The Hellenistic kingdom of Macedon ruled by the Antigonid dynasty from the third to second centuries BCE. Its armies continued the phalanx tradition until Roman conquest.
