The Universal Declaration of Human Rights (UDHR), which outlines basic human rights, was adopted by the United Nations on December 10, 1948. It was drafted primarily by the Canadian John Peters Humphrey, also counting on the help of several people from around the world.
Shaken by the recent barbarism of World War II, and with the aim of building a world under new ideological foundations, the leaders of the nations that emerged as postwar powers led by the United States and the Soviet Union established, at the Yalta Conference in Russia in 1945, the foundations of a future world peace which defined areas of influence of the powers and arranged the creation of a multilateral organization that promotes negotiations on international conflicts, to avoid wars and promote peace and democracy, and to strengthen the Human rights.
