Cyrus the Great was one of the most influential figures in history, an enlightened ruler and brilliant general who, via sword, cunning and wisdom, in the 6th century BC created the Persian Empire, largest empire known to man to that time. His army was based around one of the most famous bodyguard units in history, the Immortals, which, until Cyrus' death, was unbeaten in battle. In his newest book, bestselling author and historian Stephen Dando-Collins chronicles the life and rule of the king known as the great liberator and anointed one.
