Wrote "1st/2nd Treatise on Civil Government" as justification of Glorious Revolution and end of absolutism in England. He argued that man is born good and has rights to life, liberty, and property. To protect these rights, people enter social contract to create government with limited powers (the executive, the legislative, and the judiciary braches). If a government did not protect these rights or exceeded its authority, Locke believed the people have the right to revolt (like they did in 1688 with James II). The ideas of consent of the governed, social contract, and right of revolution influenced the United States Declaration of Independence and the U.S. Constitution. He also laid the foundations for criticism of absolute monarchy in France.
