The Constitution of the Athenians, also called the Athenian Constitution (Greek: Ἀθηναίων πολιτεία, Athenaion Politeia; Latin: Atheniensium Respublica), is a work by Aristotle or one of his students. The work describes the constitution of Classical Athens, commonly called the Areopagite constitution. Probably written by a student of Aristotle, The Athenian Constitution is both a history and an analysis of Athens' political machinery between the seventh and fourth centuries BC, which stands as a model of democracy at a time when city-states lived under differing kinds of government. While Alexander was conquering Asia, Aristotle, now 50 years old, was in Athens. Just outside the city boundary, he established his own school in a gymnasium known as the Lyceum.
