Disunity is a danger that the nations and peoples of the earth can no longer endure; the consequences are too terrible to contemplate, too obvious to require any demonstration. "The well-being of mankind," Bahá'u'lláh wrote more than a century ago, "its peace and security, are unattainable unless and until its unity is firmly established." In observing that "mankind is groaning, is dying to be led to unity, and to terminate its age-long martyrdom", Shoghi Effendi further commented that: "Unification of the whole of mankind is the hall-mark of the stage which human society is now approaching. Unity of family, of tribe, of city-state, and nation have been successively attempted and fully established. World unity is the goal towards which a harassed humanity is striving. Nation-building has come to an end. The anarchy inherent in state sovereignty is moving towards a climax. A world, growing to maturity, must abandon this fetish, recognize the oneness and wholeness of human relationships, and establish once for all the machinery that can best incarnate this fundamental principle of its life."
