With the arrival of Bahá’u’lláh at Constantinople, the capital of the Ottoman Empire and seat of the Caliphate (acclaimed by the Muhammadans as “the Dome of Islam,” but stigmatized by Him as the spot whereon the “throne of tyranny” had been established) the grimmest and most calamitous and yet the most glorious chapter in the history of the first Bahá’í century may be said to have opened. A period in which untold privations and unprecedented trials were mingled with the noblest spiritual triumphs was now commencing. The day-star of Bahá’u’lláh’s ministry was about to reach its zenith. The most momentous years of the Heroic Age of His Dispensation were at hand. The catastrophic process, foreshadowed as far back as the year sixty by His Forerunner in the Qayyúmu’l-Asmá, was beginning to be set in motion.
