United Nations Security Council Resolution 1 relating to Military Staff Committee is adopted.

United Nations Security Council Resolution 1 was adopted without a vote on 25 January 1946. The Council called for the Military Staff Committee to meet for the first time in London on 1 February 1946.

The Military Staff Committee (MSC) is the United Nations Security Council subsidiary body whose role, as defined by the United Nations Charter, is to plan UN military operations and assist in the regulation of armaments. Although the Military Staff Committee continues to exist, negotiation efforts between the United States, the Soviet Union and other nations in the late 1940s failed, and the committee has since been largely defunct, only serving in an advisory capacity.
