Polybius (//; Greek: Πολύβιος, Polýbios; c. 200 – c. 118 BC) was a Greek historian of the Hellenistic period. He is noted for his work The Histories, which covered the period of 264–146 BC and the Punic Wars in detail.
Polybius is important for his analysis of the mixed constitution or the separation of powers in government, his in-depth discussion of checks and balances to limit power, and his introduction of "the people", which influenced Montesquieu's The Spirit of the Laws, John Locke's Two Treatises of Government, and the framers of the United States Constitution.
