Article 9 of the European Convention on Human Rights provides a right to freedom of thought, conscience, and religion. This includes the freedom to change a religion or belief, and to manifest a religion or belief in worship, teaching, practice and observance, subject to certain restrictions that are "in accordance with law" and "necessary in a democratic society". Article text History was a principle of European international law, beginning in the 16th century in the wake of the Protestant reformation, that established freedom of religion for states, but not individuals. The First Amendment to the United States Constitution was one of the first legal protections for freedom of religion without reference to any specific religion. Article X of the French Declaration of the Rights of Man and of the Citizen, which influenced the European Convention, declares freedom of religious opinion as a universal right.
