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.
United Nations Security Council Resolution 745
United Nations Security Council resolution 745, adopted unanimously on 28 February 1992, after recalling resolutions 668 (1990), 717 (1991), 718 (1991) and 728 (1992), the Council, after examining a report by the Secretary-General Boutros Boutros-Ghali on 19 February 1992, authorised the establishment of the United Nations Transitional Authority in Cambodia (UNTAC), following on from the political settlement agreed in Paris on 23 October 1991. It was the first occasion where the United Nations had taken over administration of a state, as opposed to monitoring or supervising.
