Who was the leader of the Persian Army during the Persian War?

The leader of the Persian Army during the Persian Wars was Xerxes. He is best known for his role in the invasion of Greece, particularly for his leadership during key battles such as the Battle of Thermopylae and the naval Battle of Salamis in 480 BCE. Xerxes, the son of Darius I, took command after Darius's death and sought to expand the Persian Empire's influence further into Greece. His efforts were marked by significant military campaigns against various Greek city-states, ultimately aiming to avenge the earlier Persian defeat at the Battle of Marathon, which occurred during his father’s reign.

The other figures mentioned, while significant in their own right, were not in charge during the Persian Wars. Darius, Xerxes's father, was involved in the initial stages of conflict with Greece, and Cyrus, known for establishing the Persian Empire, predates both Darius and Xerxes. Xerxes II, who reigned briefly and is less well-known, did not lead the Persian army during the main Persian War conflicts.
