On 29 November 1947, the General Assembly approved a resolution to partition Palestine, approving the creation of the state of Israel. Two years later, Ralph Bunche, a UN official, negotiated an armistice to the resulting conflict. On 7 November 1956, the first UN peacekeeping force was established to end the Suez Crisis; however, the UN was unable to intervene against the USSR's simultaneous invasion of Hungary following that country's revolution.
