“most of the preeminent embodiments of power and of sovereignty in His day became, one by one, the object of Bahá’u’lláh’s special attention, and were made to sustain, in varying degrees, the weight of the force communicated by His appeals and warnings”

• The Emperor of the French, the most powerful ruler of his day on the European continent, Napoleon III;
• Pope Pius IX, the supreme head of the highest church in Christendom, and wielder of the scepter of both temporal and spiritual authority;
• the omnipotent Czar of the vast Russian Empire, Alexander II;
• the renowned Queen Victoria, whose sovereignty extended over the greatest political combination the world has witnessed;
• William I, the conqueror of Napoleon III, King of Prussia and the newly acclaimed monarch of a unified Germany;
• Francis Joseph, the autocratic king-emperor of the Austro-Hungarian monarchy, the heir of the far-famed Holy Roman Empire;
• the tyrannical ‘Abdu’l-‘Azíz, the embodiment of the concentrated power vested in the Sultanate and the Caliphate;
• the notorious Násiri’d-Dín Sháh, the despotic ruler of Persia and the mightiest potentate of Shí’ih Islám—

in a word, most of the preeminent embodiments of power and of sovereignty in His day became, one by one, the object of Bahá’u’lláh’s special attention, and were made to sustain, in varying degrees, the weight of the force communicated by His appeals and warnings.
