John Locke is a British philosopher who lived in exile in the Netherlands from 1683 to 1688, his first finished work there was "An Essay Concerning Human Understanding", which addressed human knowledge topics, related to empiricism views.

Later in the book "The Second Treatise of Government" he argues against the Divine Right of Kings doctrine, which people were born in a condition that due to God subservience they should accept the social hierarchy and be obedient to their authoritarian Kings, as they were God’s representatives in earth.

Locke advocates that humans were free and decided because of natural laws to join together as in a social contract and to give part of their rights to a government, but keeping some rights, questioning the legitimacy of absolute power. He defends the sovereignty of the people and argues about legitimacy of government by decision and reasoning, opposing to legitimacy of power taken by force or violence.
