The <em>"European Enlightenment" </em>or the<em> "Age of Reason"</em> flourished in the <em>18th century. Enlightenment Thinkers </em>focused on the conditions of the human beings and believed in the rational change of people. They valued the natural rights of humans–<u>the right to life, liberty and property</u>. This kind of thinking affected the American revolutions. It also shaped the<em> "Declaration of Independence," </em>which was used by the Americans in order to free themselves from the British control.
The "separation of powers" arosefrom the idea of John Locke and Pierre Bayle,who were<em>Enlightenment Thinkers.</em> They stated that the Church and the State should have separate powers.
