Bábís in Persia and Iraq, and surviving Bábí members of the Báb’s family, their response in support of Bahá’u’lláh was the same. Mirza Yahya’s effort to claim a divine station thus effectively cleaved him from most Bábís, for it was against the Báb’s covenant with his followers which decreed that whensoever "Him whom God shall make manifest" announced himself all Bábís were required to accept him. From this time onwards those who understood the Báb’s teachings about the Promised One began to call themselves "Bahá’ís" (meaning the people of Bahá’, followers of Bahá’u’lláh). Final exile and imprisonment in ‘Akká Having lost all respect or influence among Bábís who had become Bahá’ís, Mirza Yahya again sought to discredit Baháʼu’lláh with Ottoman authorities, accusing him of agitating against the Turkish government. Yahya’s actions provoked a government investigation, which cleared Baháʼu’lláh—but fearing religious issues might stir up future disorder, the Ottomans decided to imprison both Baháʼu'lláh and Mirza Yahya in far-flung outposts of their empire. In July 1868 a royal decree condemned Bahá’u’lláh and his family to perpetual imprisonment in the pestilential penal colony of ʻAkká; banished with them were most Bahá’ís in Adrianople, and a handful of Azalis. Mirza Yahya’s intrigue also resulted in his own captivity—because Turkish authorities suspected he was involved in some conspiracy, he was sent to prison in Famagusta, Cyprus with his family, some Azalis, and four Bahá’ís. Leaving Adrianople on 12 August 1868, Bahá’u’lláh and his companions arrived in ‘Akká on 31 August where they were incarcerated in the city's prison citadel. Inhabitants of ‘Akká were told the new prisoners were enemies of the state, of God, and his religion, and association with them was strictly forbidden. The first years in ‘Akká were under very harsh conditions with many Bahá’ís becoming sick (three eventually died). June 1870 witnessed the tragic death of Baháʼu'lláh’s 22-year-old son Mirzá Mihdí who fell through an unguarded skylight as he paced on the roof of the prison one evening while engrossed in prayer and meditation. After a while, relations between Bahá’í prisoners, officials, and the local community improved, so conditions of their imprisonment were eased. When visiting 'Akká in April 1871, Dr. Thomas Chaplin (director of a British-run hospital in Jerusalem) met with ʻAbdu'l-Bahá, on behalf of Baháʼu'lláh, in a home the family was living in after being moved out of the citadel. Afterward, the physician sent a letter regarding Baháʼu'lláh to
