The matter of international peace was instituted by His Highness, Bahá'u'lláh, sixty years ago in Persia in the year of AD 1851. From that time innumerable epistles and tablets were spread first in Persia and then in other parts of the world, until about fifty years ago He clearly stated this matter of universal peace in the Book of Aqdas and has commanded all the Bahá'ís to serve faithfully with heart and soul in this great cause, give up their possessions and wealth for it and sacrifice their lives in case of necessity. He has taught them to spread the unity of nations and religions and proclaim in all the regions of the world the oneness of the kingdom of humanity.
