Kings and emperors during Baha’u’llah’s day: - “their relation to the Faith of Bahá’u’lláh constitutes one of the most illuminating episodes in the history of the Heroic and Formative Ages of that Faith”

As to the kings and emperors who not only symbolized in their persons the majesty of earthly dominion but who, for the most part, actually held unchallengeable sway over the multitudes of their subjects, their relation to the Faith of Bahá’u’lláh constitutes one of the most illuminating episodes in the history of the Heroic and Formative Ages of that Faith. The Divine summons which embraced within its scope so large a number of the crowned heads of both Europe and Asia; the theme and language of the Messages that brought them into direct contact with the Source of God’s Revelation; the nature of their reaction to so stupendous an impact; and the consequences which ensued and can still be witnessed today are the salient features of a subject upon which I can but inadequately touch, and which will be fully and befittingly treated by future Bahá’í historians.

“From two ranks amongst men power hath been seized: kings and ecclesiastics.” – “the dire consequences” of their rejection of the Divine Message

Small wonder, then, that the Author of the Bahá’í Faith, and to a lesser degree its Herald, should have directed at the world’s supreme rulers and religious leaders the full force of Their Messages, and made them the recipients of some of Their most sublime Tablets, and invited them, in a language at once clear and insistent, to heed Their call. Small wonder that They should have taken the pains to unroll before their eyes the truths of Their respective Revelations, and should have expatiated on Their woes and sufferings. Small wonder that They should have stressed the preciousness of the opportunities which it was in the power of these rulers and leaders to seize, and should have warned them in ominous tones of the grave responsibilities which the rejection of God’s Message would entail, and should have predicted, when rebuffed and refused, the dire consequences which such a rejection involved. Small wonder that He Who is the King of kings and Vicegerent of God Himself should, when abandoned, contemned and persecuted, have uttered this epigrammatic and momentous prophecy: “From two ranks amongst men power hath been seized: kings and ecclesiastics.”

“the kings of the earth and the world’s religious leaders… were made the direct recipients of the Message proclaimed by both the Báb and Bahá’u’lláh”

It should not be forgotten that it was the kings of the earth and the world’s religious leaders who, above all other categories of men, were made the direct recipients of the Message proclaimed by both the Báb and Bahá’u’lláh. It was they who were deliberately addressed in numerous and historic Tablets, who were summoned to respond to the Call of God, and to whom were directed, in clear and forcible language, the appeals, the admonitions and warnings of His persecuted Messengers. It was they who, when the Faith was born, and later when its mission was proclaimed, were still, for the most part, wielding unquestioned and absolute civil and ecclesiastical authority over their subjects and followers. It was they who, whether glorying in the pomp and pageantry of a kingship as yet scarcely restricted by constitutional limitations, or entrenched within the strongholds of a seemingly inviolable ecclesiastical power, assumed ultimate responsibility for any wrongs inflicted by those whose immediate destinies they controlled. It would be no exaggeration to say that in most of the countries of the European and Asiatic continents absolutism, on the one hand, and complete subservience to ecclesiastical hierarchies, on the other, were still the outstanding features of the political and religious life of the masses. These, dominated and shackled, were robbed of the necessary freedom that would enable them to either appraise the claims and merits of the Message proffered to them, or to embrace unreservedly its truth.

The “trials which have afflicted the Faith of Bahá’u’lláh”: -> “The kings of the earth and the world’s religious leaders alike must primarily bear the brunt of such an awful responsibility.”

Dear friends! For the trials which have afflicted the Faith of Bahá’u’lláh a responsibility appalling and inescapable rests upon those into whose hands the reins of civil and ecclesiastical authority were delivered. The kings of the earth and the world’s religious leaders alike must primarily bear the brunt of such an awful responsibility. “Everyone well knoweth,” Bahá’u’lláh Himself testifies, “that all the kings have turned aside from Him, and all the religions have opposed Him.” “From time immemorial,” He declares, “they who have been outwardly invested with authority have debarred men from setting their faces towards God. They have disliked that men should gather together around the Most Great Ocean, inasmuch as they have regarded, and still regard, such a gathering as the cause of, and the motive for, the disruption of their sovereignty.” “The kings,” He moreover has written, “have recognized that it was not in their interest to acknowledge Me, as have likewise the ministers and the divines, notwithstanding that My purpose hath been most explicitly revealed in the Divine Books and Tablets, and the True One hath loudly proclaimed that this Most Great Revelation hath appeared for the betterment of the world and the exaltation of the nations.” “Gracious God!” writes the Báb in the Dalá’il-i-Sab‘ih (Seven Proofs) with reference to the “seven powerful sovereigns ruling the world” in His day, “None of them hath been informed of His [the Báb’s] Manifestation, and if informed, none hath believed in Him. Who knoweth, they may leave this world below full of desire, and without having realized that the thing for which they were waiting had come to pass. This is what happened to the monarchs that held fast unto the Gospel. They awaited the coming of the Prophet of God [Muhammad], and when He did appear, they failed to recognize Him. Behold how great are the sums which these sovereigns expend without even the slightest thought of appointing an official charged with the task of acquainting them in their own realms with the Manifestation of God! They would thereby have fulfilled the purpose for which they have been created. All their desires have been and are still fixed upon leaving behind them traces of their names.” The Báb, moreover, in that same treatise, censuring the failure of the Christian divines to acknowledge the truth of Muhammad’s mission, makes this illuminating statement: “The blame falleth upon their doctors, for if these had believed, they would have been followed by the mass of their countrymen. Behold then, that which hath come to pass! The learned men of Christendom are held to be learned by virtue of their safeguarding the teaching of Christ, and yet consider how they themselves have been the cause of men’s failure to accept the Faith and attain unto salvation!”

Bahá’u’lláh’s prophesy concerning the drastic changes that the world will go through

“Soon,” Bahá’u’lláh Himself has prophesied, “will the present-day order be rolled up, and a new one spread out in its stead.” And again: “By Myself! The day is approaching when We will have rolled up the world and all that is therein, and spread out a new Order in its stead.” “The day is approaching when God will have raised up a people who will call to remembrance Our days, who will tell the tale of Our trials, who will demand the restitution of Our rights, from them who, without a tittle of evidence, have treated Us with manifest injustice.”
