The first epoch [1921-1944] witnessed the birth and the primary stages in the erection of the framework of the Administrative Order of the Faith — the nucleus and pattern of its World Order — according to the precepts laid down in ‘Abdu’l-Bahá’s Will and Testament, as well as the launching of the initial phase of the world-encompassing Plan bequeathed by Him to the American Bahá’í Community. That epoch was characterized by a twofold process aiming at the consolidation of the administrative structure of the Faith and the extension of the range of its institutions. It witnessed on the one hand, the emergence and the laying of the groundwork of that embryonic World Order whose advent was announced by the Báb in the Bayán, whose laws were revealed by Bahá’u’lláh in the Kitáb-i-Aqdas, and whose features were delineated by ‘Abdu’l-Bahá in His Will and Testament. It was marked on the other hand by the launching, in the Western Hemisphere, of the first stage of a Plan whose original impulse was communicated by the Herald of our Faith in His Qayyúmu’l-Asmá, to whose implications the Author of the Bahá’í Revelation alluded in His Tablets, and whose Charter was revealed by the Center of His Covenant in the evening of His life.
