The Universal Declaration of Human Rights has been called a Magna Carta for all humanity. Pope John Paul II described it as "one of the highest expressions of the human conscience of our time".
Its adoption marked the first time in history that people from different cultures had worked together to identify a common vision of the specific rights and freedoms of all human beings.
How did the declaration come into being?
In 1945, following the horrors of World War II and the Holocaust, a number of governments said "never again", and drew up the United Nations Charter. A commission "for the promotion of human rights", chaired by the former US First Lady, Eleanor Roosevelt, was also established.
Differences in language and values made drafting the UDHR a marathon of meetings and negotiations. The world's major legal systems and legal philosophies had to be considered and religions including Buddhism, Christianity, Confucianism, Hindu, Islam and Judaism.
How long did it take?
The Commission was created in 1946. It completed its proposed declaration in June 1948. The final draft went to the full General Assembly on 6 December 1948. On 10 December, 48 states voted to adopt it. None voted against, eight abstained.
What is in the declaration?
It consists of a preamble and 30 articles, setting forth the human rights and fundamental freedoms to which all people, everywhere, are entitled.
It identifies civil and political rights such as the right not to be subjected to torture, to equality before the law, to a fair trial, to freedom of movement, to asylum and to freedom of thought, conscience, religion, opinion and expression.
Article 1: All human beings are born free and equal
Article 3: Everyone has the right to life, liberty and security
Article 4: No-one shall be held in slavery or servitude
Article 5: No-one shall be subjected to torture
Article 9: No-one shall be subjected to arbitrary arrest
Article 18: Everyone has the right to freedom of thought
It also includes economic, social and cultural rights such as the right to food, clothing, housing and medical care, to social security, to work, to equal pay for equal work, to form trade unions and to education.
What has the declaration achieved?
Over the past 50 years the Universal Declaration has become a powerful tool in the armoury of those trying to dissuade governments from violating human rights. Many lawyers regard it as part of customary international law.
Along with the UN Charter, it has provided the moral and legal basis for United Nations action - including action by the Security Council - against violators of human rights.
Countries have included the language and principles of the UDHR in their national constitutions, and in their statutory laws and regulations. The Convention for the Protection of Human Rights and Fundamental freedoms adopted by the Council of Europe in 1950, and Article II of the Charter of the Organisation of African Unity are two examples of documents which draw heavily on the UDHR.
