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.
1961 United Nations Secretary-General selection
The Security Council met in closed session on 3 November 1961, unanimously adopting Resolution 168 to recommend U Thant to the General Assembly. A resolution was presented that afternoon by Ceylon, Liberia, and the United Arab Republic, all of them non-permanent members of the Security Council. The United States and the Soviet Union could not sponsor the resolution, as the other permanent members would have joined as co-sponsors, and the Soviet Union did not accept the participation of Nationalist China.
