The date was chosen to honour the United Nations General Assembly’s adoption and proclamation, on 10 December 1948, of the Universal Declaration of Human Rights (UDHR), the first global enunciation of human rights and one of the first major achievements of the new United Nations. The formal establishment of Human Rights Day occurred at the 317th Plenary Meeting of the General Assembly on 4 December 1950, when the General Assembly declared resolution 423(V), inviting all member states and any other interested organizations to celebrate the day as they saw fit.

John Piper: Just a reminder on World Human Rights Day, there is no such thing in relation to God, only in relation to men.
