After two years He returned to Ba_gh_dád. Friends He had known in Sulimaniyye came to visit Him. They found Him in his accustomed environment of ease and affluence and were astonished at the appointments of one who had lived in seclusion under such frugal conditions in Kurdistán. The Íránian government believed the banishment of the Blessed Perfection from Írán would be the extermination of His Cause in that country. These rulers now realized that it spread more rapidly. His prestige increased, His teachings became more widely circulated. The chiefs of Írán then used their influence to have Bahá’u’lláh exiled from Ba_gh_dád. He was summoned to Constantinople by the Turkish authorities. While in Constantinople He ignored every restriction, especially the hostility of ministers of state and clergy. The official representatives of Írán again brought their influence to bear upon the Turkish authorities and succeeded in having Bahá’u’lláh banished from Constantinople to Adrianople, the object being to keep Him as far away as possible from Írán and render His communication with that country more difficult. Nevertheless the Cause still spread and strengthened. Finally they consulted together and said: “We have banished Bahá’u’lláh from place to place but each time he is exiled his cause is more widely extended, his proclamation increases in power and day by day his lamp is becoming brighter. This is due to the fact that we have exiled him to large cities and populous centers. Therefore we will send him to a penal colony as a prisoner so that all may know he is the associate of murderers, robbers and criminals; in a short time he and his followers will perish.” The sultan of Turkey then banished Him to the prison of Akká in Syria. When Bahá’u’lláh arrived at Akká, through the power of God He was able to hoist His banner. His light at first had been a star; now it became a mighty sun and the illumination of His Cause expanded from the east to the west. Inside prison walls He wrote epistles to all the kings and rulers of nations summoning them to arbitration and Universal Peace. Some of the kings received His words with disdain and contempt. One of these was the sultan of the Ottoman kingdom. Napoleon III of France did not reply. A second epistle was addressed to him. It stated: “I have written you an epistle before this, summoning you to the cause of God but you are of the heedless. You have proclaimed that you were the defender of the oppressed; now it hath become evident that you are not. Nor are you kind to your own suffering and oppressed people. Your actions are contrary to your own interests and your kingly pride must fall. Because of your arrogance God shortly will destroy your sovereignty. France will flee away from you and you will be overwhelmed by a great conquest. There will be lamentation and mourning, women bemoaning the loss of their sons.” This arraignment of Napoleon III was published and spread.
