A result of the abuses that had occurred in Europe during the 2nd World War.
The Universal Declaration of Human Rights (UDHR) is a milestone document in the history of human rights. Drafted by representatives with different legal and cultural backgrounds from all regions of the world, the Declaration was proclaimed by the United Nations General Assembly in Paris on the 10 of December 1948 as a common standard of achievements for all peoples and all nations. It sets out, for the first time, fundamental human rights to be universally protected and it has been translated into over 500 languages.
Some of the declared rights:
Equal rights of men and women
equality before the law
presumed innocent until proven guilty
education rights
freedom from torture or inhumane punishment
freedom of thought
freedom of opinion and conscience
freedom of religion
freedom of peaceful assembly
freedom of association
A Canadian at the heart of its creation:
Canadian John Peters Humphrey appointed as the first Director of the Human Rights Division of the United Nations Secretariat, was the principal drafter of the Universal Declaration of Human Rights. After consulting with the executive group of the Commission, chaired by Eleanor Roosevelt, Professor Humphrey prepared the first preliminary draft of what was to become the Universal Declaration of Human Rights and was dubbed by Mrs. Roosevelt as "the international Magna Carta of all mankind".
