What UN resolution ended the Yom Kippur War?

United Nations Security Council Resolution 338 called for the ceasefire that ended the Yom Kippur War.

The Security Council adopted Resolution 338 on October 22, 1973, during the final stage of the conflict. It demanded that the parties stop all military activity within 12 hours and called for implementation of Resolution 242, the post–Six-Day War framework concerning withdrawal, borders, and a negotiated settlement.

Resolution 338 also called for negotiations between the combatants. It was adopted by a vote of 14 in favor, none against, with China abstaining. The resolution reflected Cold War diplomacy: the United States and Soviet Union jointly pressed for an end to the fighting and for negotiations.

The ceasefire did not immediately eliminate every clash. Fighting continued in places, especially around the Egyptian Third Army, and Resolution 340 was adopted on October 25 to reinforce the ceasefire and create a UN emergency force. Nevertheless, Resolution 338 is the standard answer because it initiated the ceasefire and formally set the diplomatic process in motion.
