Quick Answer: Xerxes I was the King of Persia from 486 to 465 BCE, known for invading Greece during the Second Persian War. He led a massive army of ~200,000 soldiers and 1,200 ships at the Battle of Thermopylae in 480 BCE.

Key Facts

Overview

Xerxes I, also known as Xerxes the Great, was the fourth King of Kings of the Achaemenid Empire, reigning from 486 to 465 BCE. He was the son of Darius I and Atossa, daughter of Cyrus the Great, giving him a direct lineage to Persia’s founding monarch.

His reign is most notable for the Second Persian invasion of Greece, a campaign aimed at avenging his father’s defeat at Marathon. Though initially successful, the invasion ultimately failed after defeats at Salamis and Plataea, marking a turning point in Persian expansion.

How It Works

Xerxes ruled through a centralized imperial system supported by regional governors and a powerful military. His authority was justified by divine right and Persian tradition.
