"Αθηναίων Πολιτεία" by Aristotle is a treatise written between 330 and 322 BCE. It examines the political system of ancient Athens through two parts: a historical account tracing constitutional changes from archaic times through various reforms and regimes, and a detailed description of governmental institutions including magistrates, courts, and public officials. The work survives as the only remaining example from Aristotle's collection of 158 constitutions of Greek city-states, discovered on papyrus in Egypt in 1879.
