The 30th Anniversary Special Edition of The Promise of World Peace, prepared for publication by the Bahá'í Chair for World Peace at the University of Maryland, College Park, compiles the original 1985 message from the Universal House of Justice to the peoples of the world in ten languages: Arabic, Chinese, English, French, Hindi, Persian, Portuguese, Russian, Spanish, and Swahili. The statement calls attention to the value of establishing agreement on principles from which people of goodwill can devise practical solutions to the barriers to peace.
