John Locke was an English philosopher born in 1632 who wrote influential works on political philosophy and theories of government. He believed that governments derive their power from the consent of the governed, that people have natural rights like life, liberty and property, and that governments are bound by civil and natural law to protect those rights. If governments fail to protect rights or abuse their power, people have a right to revolt and change the government. Many of Locke's ideas about natural rights, limited government, and consent of the governed influenced the writers of the U.S. Constitution.
