Adopted and proclaimed on 10 December 1948 by the General Assembly of the United Nations, the Universal Declaration of Human Rights contains 30 articles that have been embedded in international treaties, national constitutions and other laws. The declaration is one of the cornerstones of the International Bill of Human Rights, which became law in 1976.
The full declaration sets out the basic rights all people should enjoy and expect from their governments and other governments. Though the declaration is often ignored, it represents the ideal that the world’s government should strive to meet.
Article 18 and Article 19 deal with freedom of thought and freedom of expression most directly, though other articles also reference these fundamental rights.

Article 19 of the Universal Declaration of Human Rights
Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers.
