United Nations Security Council
The UN officially came into existence on 24 October 1945 upon ratification of the Charter by the five then-permanent members of the Security Council and by a majority of the other 46 signatories. On 17 January 1946, the Security Council met for the first time at Church House, Westminster, in London, United Kingdom.
First emergency special session of the United Nations General Assembly
The first emergency special session of the United Nations General Assembly was convened on 1 November and ended on 10 November 1956 resolving the Suez Crisis by creating the United Nations Emergency Force to provide an international presence between the belligerents in the canal zone. The emergency special session was convened due to the failure of the Security Council to resolve the instability at the Suez Canal, invoking "Uniting for Peace" resolution which transferred the issue from the Security Council to the General Assembly. On the fourth day of the session the Canadian representative, Lester B. Pearson, introduced the concept of a UN police force. The creation of the United Nations Emergency Force (the first peacekeeping force) was approved by the General Assembly with 57 supports and zero opposes. The vote had 19 countries abstaining, including the United Kingdom, France, Egypt, the Soviet Union and several Eastern European countries.
