Darius the Great

A biography of Darius I, the Persian king who conquered Egypt and defeated the Greeks at Marathon.

Darius, son of Hystaspes, rose from obscurity to become ruler of the Persian Empire after a series of political assassinations and power struggles. His reign began with the destruction of Babylon, which had rebelled against Persian rule, and continued with ambitious military campaigns across Asia Minor and into Greece. Darius's forces landed at Marathon in 490 BCE, seeking to conquer mainland Greece, but faced a determined Greek resistance led by Miltiades. The Persian army, despite its overwhelming numbers, suffered a devastating defeat at the hands of the Greek hoplites. This battle marked the first major defeat of a Persian invasion force, reshaping the course of ancient history and establishing Darius's legacy as a ruler whose ambition was ultimately checked by the courage and tactical skill of the Greeks.
