The Declaration of the Rights of Man and the Citizen
The Reformation, the Enlightenment, and the French Revolution led to the end of the ancient Western monarchical and feudal system. The Declaration of the Rights of Man and the Citizen (1789) is a document of fundamental importance from that period. It sets forth universal, fundamental, inalienable, human rights. Strange, though, such a document served as impulse to the Reign of Terror. Image links to the Yale Law School translation.
Council of Trent
Events in Western Christendom, beginning on 31 October 1517, led to widespread revolt against and abandonment of the Roman Catholic Church. Finally in 1545, Pope Paul III was able to convoke a council in Trent (A.D. 1545-63) in order to form a definitive response to the assertions of the Protestants and to effect a general reform of the Church. The Council of Trent is regarded as ecumenical by the Holy See and the initiation of the Counter-Reformation. Image above links to Buckley translation of the Council’s canons and decrees.
