The Greatest General in History? Alexander the Great (All Parts)

Overview

Alexander the Great used the Macedonian army—especially its sarissa-armed phalanx and Companion Cavalry—to defeat Persian forces at Granicus, Issus, and Gaugamela, then conquered territory from Egypt to India in a decade-long campaign. His empire stretched from Greece to Pakistan, but endless campaigning, conflict over Persian customs, and the absence of a succession plan left it unstable after his death at 32; its fragmentation nevertheless spread Greek culture into the Hellenistic world.

Key takeaways

Alexander's army combined the 18-foot sarissa phalanx with elite cavalry, allowing him to pin opponents in place and exploit openings with rapid attacks at battles such as Issus and Gaugamela.
At Gaugamela, Alexander's outward movement deliberately drew Persian troops away from Darius's center; a concentrated Companion Cavalry charge then broke the weakened line.
Alexander's conquests relied on both force and political incorporation: he retained loyal Persian officials, founded cities across the eastern provinces, and arranged marriages linking Macedonian officers to Persian nobility.
The long eastern campaigns and Alexander's adoption of Persian court practices alienated Macedonian troops, contributing to resistance at the Hyphasis and mutiny at Opis.
Alexander's empire depended heavily on his personal authority; without a succession plan, his generals fought over it, while Greek culture continued to spread through the successor kingdoms.
