Though Bahá’u’lláh had been banished from His native land, the tide of calamity which had swept with such fury over Him and over the followers of the Báb, was by no means receding. Under the jurisdiction of the Sulṭán of Turkey, the arch-enemy of His Cause, a new chapter in the history of His ever-recurring trials had opened. The overthrow of the Sultanate and the Caliphate, the twin pillars of Sunní Islám, can be regarded in no other light except as the inevitable consequence of the fierce, the sustained and deliberate persecution which the monarchs of the tottering House of U_th_mán, the recognized successors of the Prophet Muḥammad, had launched against it. From the city of Constantinople, the traditional seat of both the Sultanate and the Caliphate, the rulers of Turkey had, for a period covering almost three quarters of a century, striven, with unabated zeal, to stem the tide of a Faith they feared and abhorred. From the time Bahá’u’lláh set foot on Turkish soil and was made a virtual prisoner of the most powerful potentate of Islám to the year of the Holy Land’s liberation from Turkish yoke, successive Caliphs, and in particular the Sulṭáns ‘Abdu’l-‘Azíz and ‘Abdu’l-Ḥamíd, had, in the full exercise of the spiritual and temporal authority which their exalted office had conferred upon them, afflicted both the Founder of our Faith and the Center of His Covenant with such pain and tribulation as no mind can fathom nor pen or tongue describe. They alone could have measured or borne them. To these afflictive trials Bahá’u’lláh has repeatedly testified: “By the righteousness of the Almighty! Were I to recount to thee the tale of the things that have befallen Me, the souls and minds of men would be incapable of sustaining its weight. God Himself beareth Me witness.” “Twenty years have passed,” He, addressing the kings of Christendom, has written, “during which We have, each day, tasted the agony of a fresh tribulation. No one of them that were before Us hath endured the things We have endured. Would that ye could perceive it! They that rose up against us have put us to death, have shed our blood, have plundered our property, and violated our honor.” “Recall to mind My sorrows,” He, in another connection, has revealed, “My cares and anxieties, My woes and trials, the state of My captivity, the tears that I have shed, the bitterness of Mine anguish, and now Mine imprisonment in this far-off land... Couldst thou be told what hath befallen the Ancient Beauty, thou wouldst flee into the wilderness, and weep with a great weeping... Every morning I arose from my bed, I discovered the hosts of countless afflictions massed behind My door; and every night when I lay down, lo, My heart was torn with agony at what it had suffered from the fiendish cruelty of its foes.”
