Cyropaedia is a biography of Cyrus the Great, the founder of Achaemenid Empire and the first Persian Empire. It is "a political romance, describing the education of the ideal ruler, trained to rule as a benevolent despot over his admiring and willing subjects." Aspects of it would become a model for medieval writers of the genre known as mirrors for princes. In turn it was a strong influence upon the most well-known but atypical of these, Machiavelli's The Prince.

Xenophon of Athens (c. 431 BC – 354 BC) was an ancient Greek philosopher, historian, soldier, mercenary, and student of Socrates. Xenophon's works span several genres and are written in plain-language Attic Greek, for which reason they serve as translation exercises for contemporary students of the Ancient Greek language. As a historian, Xenophon is known for recording the history of his time, the late-5th and early-4th centuries BC, in such works as the Hellenica, which covered the final seven years and the aftermath of the Peloponnesian War (431–404 BC), thus representing a thematic continuation of Thucydides' History of the Peloponnesian War.
