Spanning a mere decade, Alexander the Great’s conquests from 336 to 323 BCE forged one of history’s largest empires, stretching from Greece across Asia to Egypt. Despite its brief existence, his empire forged a profound impact, blending cultures and disseminating Greek ideas, instigating an era known as the Hellenistic Period.
