On 30 October 1943, the Declaration of the Four Nations, one of the four Moscow Declarations, was signed by the foreign ministers of the Big Four, calling for the establishment of a "general international organization, based on the principle of the sovereign equality of all peace-loving states, and open to membership by all such states, large and small, for the maintenance of international peace and security.” This was the first formal announcement that a new international organization was being contemplated to replace the moribund League of Nations.
