Alexander Conquers Persia
The world bowed to a 25-year-old king
On the dusty plains of Gaugamela in modern-day Iraq, a young Macedonian king led his outnumbered forces against the vast Persian army of Darius III. Through brilliant cavalry tactics and sheer audacity, Alexander the Great shattered the Achaemenid Empire in a single afternoon. The victory opened the gates of Babylon and made Alexander master of the known world.
