The Two Treatises of Government (or "Two Treatises of Government: In the Former, The False Principles and Foundation of Sir Robert Filmer, And His Followers, are Detected and Overthrown. The Latter is an Essay concerning The True Original, Extent, and End of Civil-Government") is a work of political philosophy published anonymously in 1689 by John Locke. The First Treatise attacks patriarchalism in the form of sentence-by-sentence refutation of Robert Filmer's Patriarcha and the Second Treatise outlines his ideas for a more civilized society based on natural rights and contract theory.

John Locke (29 August 1632 � 28 October 1704), widely known as the Father of Classical Liberalism,was an English philosopher and physician regarded as one of the most influential of Enlightenment thinkers.
