Biography

Alexander the Great: life and legacy

Life and career

Alexander inherited Philip II's powerful Macedonian kingdom and invaded the Achaemenid Empire in 334 BC. Victories carried his army from the eastern Mediterranean to Egypt, central Asia and India. His early death fractured the empire while accelerating cultural and political exchange across the Hellenistic world.

Historical context

Ancient evidence is incomplete and often written by elites. Later admiration can turn contested political actors into timeless heroes, so contemporary context and source limits matter.

Legacy and interpretation

Alexander the Great's reputation has been shaped by commemoration, political argument and the survival of unequal evidence. A responsible biography compares contemporary records with later interpretation, recognises people affected by their decisions and avoids reducing broad change to one famous life.
