The Persian Immortal Guards (Anusiya in Old Persian) were the elite 10,000-strong infantry unit of the Achaemenid Empire, serving as the personal bodyguard of the Persian King and the backbone of imperial military power. Established by Cyrus the Great in the 6th century BCE, these legendary warriors earned their name from their unwavering commitment to duty: whenever a soldier fell in battle, he was immediately replaced to maintain the unit’s perfect strength of 10,000. This policy symbolized the empire’s infinite resources, unbreakable resolve, and the immortality of Persian sovereignty itself.
Clad in distinctive colorful robes, golden armor, and ornate helmets, the Immortals carried spears with silver pomegranate counterbalances—symbols of fertility, abundance, and royal authority. They fought at pivotal battles including Marathon (490 BCE) and Thermopylae (480 BCE), earning respect across the ancient world for their discipline, loyalty, and martial excellence. Under commanders like Mardonius, they represented not merely military force but the embodiment of Persian imperial ideology: unity, order, and the divine right of the Achaemenid throne.
Today, the Persian Immortal Guards symbolize the restoration of Persian military pride, national defense, and the eternal vigilance required to protect Iran’s sovereignty and territorial integrity. The Kingdom of Persia honors this legacy as a model of elite service, unwavering loyalty to the nation, and the sacrifice demanded of those who stand as guardians of the realm.
