1848-1850: “the bloodiest and most dramatic of the Heroic Age of the Bahá’í Era”

The Báb’s captivity in a remote corner of Ádhirbáyján, immortalized by the proceedings of the Conference of Badasht, and distinguished by such notable developments as the public declaration of His mission, the formulation of the laws of His Dispensation and the establishment of His Covenant, was to acquire added significance through the dire convulsions that sprang from the acts of both His adversaries and His disciples. The commotions that ensued, as the years of that captivity drew to a close, and that culminated in His own martyrdom, called forth a degree of heroism on the part of His followers and a fierceness of hostility on the part of His enemies which had never been witnessed during the first three years of His ministry. Indeed, this brief but most turbulent period may be rightly regarded as the bloodiest and most dramatic of the Heroic Age of the Bahá’í Era.

1873: Second trumpet-blast and its resulting effects on the Muslim world

Accelerated, twenty years later, by another trumpet-blast, announcing the formulation of the laws of yet another Dispensation, this process of disintegration, associated with the declining fortunes of a superannuated, though divinely revealed Law, gathered further momentum, precipitated, in a later age, the annulment of the Sharí‘aḥ canonical Law in Turkey, led to the virtual abandonment of that Law in Shí‘ah Persia, has, more recently, been responsible for the dissociation of the System envisaged in the Kitáb-i-Aqdas from the Sunní ecclesiastical Law in Egypt, has paved the way for the recognition of that System in the Holy Land itself, and is destined to culminate in the secularization of the Muslim states, and in the universal recognition of the Law of Bahá’u’lláh by all the nations, and its enthronement in the hearts of all the peoples, of the Muslim world.
