"Treatise of Government" is one of the great classics of Political Philosophy. Its author, John Locke, became one of the greatest philosophers of liberalism and democracy, and his ideas remain relevant and are studied to this day. Locke's thoughts influenced important events in history, particularly in Europe and America. He is often called the theorist of the English Revolution (1688) and was the main source of ideas for the American Revolution (1776), influencing the Declaration of Independence and the state constitutions of that country. In "Second Treatise of Government," John Locke expresses his liberal thinking and his position against absolutist governments with arguments that demonstrate that government emanates from the people and that, together with the law, should be used for the common good.
