The General Assembly of U.N.O. passed the Declaration of Human Rights on

Concept

The Universal Declaration of Human Rights (UDHR) is the foundational UN General Assembly instrument that lays down a common standard of civil, political, social, economic, and cultural rights for all nations. It was drafted by the UN Commission on Human Rights (chaired by Eleanor Roosevelt) after the UN's founding in 1945, in direct response to the atrocities of the Second World War, and required a formal General Assembly resolution to be adopted.

Application

1. The Commission on Human Rights was set up by the UN Economic and Social Council in 1946 and spent 1947 drafting successive versions of the rights charter.

2. The final text was placed before the UN General Assembly, then meeting in Paris, and was adopted on 10 December 1948 through Resolution 217 A (III).

3. This vote is the origin of Human Rights Day, observed every year on 10 December in memory of the 1948 adoption.

Cross-check

The UN's own historical record and the resolution number (217 A (III)) both confirm 10 December 1948 as the adoption date, so the answer is independently verifiable from the UN's official archives, not just textbook recall.
