The Macedonian Empire, led by Alexander the Great, is notable for its use of the phalanx in warfare. This tactical formation comprised heavily armed infantry soldiers (hoplites) arranged in close ranks, typically eight rows deep, allowing for significant defensive and offensive capabilities. The phalanx allowed Macedonian forces to advance or hold their position effectively against various adversaries. Alexander's innovative military strategies improved this formation and contributed to his conquests across Asia. His adaptations to the traditional phalanx enabled him to achieve unprecedented success, ultimately leading to the expansion of his empire and influence on military tactics for generations to come.
