United Nations Security Council Resolution 242 (S/RES/242) was adopted unanimously by the UN Security Council on November 22, 1967, in the aftermath of the Six-Day War. It was adopted under Chapter VI of the UN Charter. The resolution was sponsored by British ambassador Lord Caradon and was one of five drafts under consideration.
The preamble refers to the "inadmissibility of the acquisition of territory by war and the need to work for a just and lasting peace in the Middle East in which every State in the area can live in security".
