Third session of the United Nations General Assembly in the context of "1948 Genocide Convention"

The Universal Declaration of Human Rights (UDHR) is an international document adopted by the United Nations General Assembly that codifies some of the rights and freedoms of all human beings. Drafted by a United Nations (UN) committee chaired by Eleanor Roosevelt, it was accepted by the General Assembly as Resolution 217 during its third session on 10 December 1948 at the Palais de Chaillot in Paris, France. Of the 58 members of the UN at the time, 48 voted in favour, none against, eight abstained, and two did not vote.

A foundational text in the history of human and civil rights, the Declaration consists of 30 articles detailing an individual's "basic rights and fundamental freedoms" and affirming their universal character as inherent, inalienable, and applicable to all human beings. Adopted as a "common standard of achievement for all peoples and all nations", the UDHR commits nations to recognize all humans as being "born free and equal in dignity and rights" regardless of "nationality, place of residence, sex, national or ethnic origin, colour, religion, language, or any other status".

The Convention on the Prevention and Punishment of the Crime of Genocide (CPPCG), or the Genocide Convention, is an international treaty that criminalizes genocide and obligates state parties to pursue the enforcement of its prohibition. It was the first legal instrument to codify genocide as a crime and the first human rights treaty unanimously adopted by the United Nations General Assembly on 9 December 1948, during the third session of the United Nations General Assembly. The Convention entered into force on 12 January 1951 and has 153 state parties as of February 2025.

The Genocide Convention was conceived largely in response to World War II, which saw atrocities such as the Holocaust that lacked an adequate description or legal definition. Polish-Jewish lawyer Raphael Lemkin, who had coined the term genocide in 1944 to describe Nazi policies in occupied Europe and the Armenian genocide, campaigned for its recognition as a crime under international law. Lemkin also linked colonialism with genocide, mentioning colonial genocides outside of Europe in his writings. In a 1946 resolution, the General Assembly recognized genocide as an international crime and called for the creation of a binding treaty to prevent and punish its perpetration. Subsequent discussions and negotiations among UN member states resulted in the CPPCG.
