Another comet seemed to reappear at significant times in history. The first recorded sighting for the comet that came to be known as Biela's Comet was made in 1772 with a second appearance in 1805. In 1826 Wilhelm von Biela and others contributed to work to determine that it was indeed the same comet making reappearances in elliptical orbit with an orbital period of 6.6 years.

In the 1845-1846 appearance astronomers were surprised to see that the comet had split into two pieces. By 1852 only one nucleus remained visible. The 1859 apparition was very unfavourable but that of 1865-1866 was more visible. Astronomers believed that the comet had broken up and accounted for an unusual number of meteor showers. At the comet's next return in 1872 a major meteor storm occurred on the 27th of November with hourly rates of 3,000 per hour. Intense meteor displays were also noted in 1885 (15,000/hr), and 1892 (6,000/hr). [Cometography; Thief in the Night p195-196; Release the Sun p217-219]

To set the context, this came during the period known as "Tanzimat" (lit. Reorganization) 1838 to 1876. The Tanzimat era was characterised by various attempts to modernise the Ottoman Empire and to secure its territorial integrity against internal nationalist movements and external aggressive powers. The reforms encouraged Ottomanism among the diverse ethnic groups of the Empire and attempted to stem the tide of the rise of nationalism in the Ottoman Empire. During the Tanzimat period, the government's series of constitutional reforms led to a fairly modern conscripted army, banking system reforms, the decriminalization of homosexuality, the replacement of religious law with secular law and guilds with modern factories. The Ottoman Ministry of Post was established in Istanbul in 1840. [Wikipedia]

The fulfillment of the prophecies of Christ and of the Bible has been over a period of a hundred years or more matter of common knowledge and remark in the West. But the full extent of that fulfillment is only seen in Bahá'u'lláh. The proclamation of His Faith was made in 1844, the year when the strict exclusion of the Jews from their own land enforced by the Muslims for some twelve centuries was at last relaxed by the Edict of Toleration and "the times of the Gentiles" were "fulfilled." [GPBiv Introduction by George Townshend]

Two hours and eleven minutes after sunset Siyyid `Alí-Muhammad made His declaration to Mullá Husayn-i-Bushrú'í in the upper room of His House. [DB52-65]

"I am, I am, I am, the promised One! I am the One whose name you have for a thousand years invoked, at whose mention you have risen, whose advent you have longed to witness, and the hour of whose Revelation you have prayed God to hasten. Verily I say, it is incumbent upon the peoples of both the East and the West to obey My word and to pledge allegiance to My person." [DB315-316]

Among those attracted was the personal court physician during the Qájár Dynasty, Hakím Masíh, who first learned about the Faith when he was accompanying Muhammad Sháh to Karbila. While en route he encountered Tahirih in Baghdad, who was giving a lecture. He also met with her personally and observed her interactions with the divines. Years later he was called upon to treat a child, Ibn -I-Asdaq, who, with his father Ismu'lláhu'l-Asdaq, were chained together in the Siyáh-Chál for two years and four months. For a period of two months he visited the child regularly and learned more of the Faith from his father. Hakím Masíh taught the Faith to his family and this was the start of the Jewish conversion in Hamadán and Káshan. He was favoured by a number of tablets from Bahá'u'llah and his youngest grandson, Dr Lutfu'lláh h Hakím served the Master as well as Shoghi Effendi and was elected to the first Universal House of Justice in 1963. [Rob3p265-268]

The governor offered all of his resources to try to win the Sháh over to His Cause but the Báb declined his offer saying that the Cause will triumph through the `poor and lowly'. [Bab115–16; DB212–213]

Some accounts maintain that the prime minister intervened in the correspondence between the Báb and the Sháh. En route to Tabríz the Báb wrote to various people, including the Grand Vizier, the father and uncle of Táhirih, and Hájí Sulaymán Khán. Hujjat learned of this last letter and sent a message to the Bábís of Zanján to rescue the Báb. The Báb declined their assistance. [Bab124–5; DB235–6]

At the beginning of the Báb's incarceration the warden `Alí Khán kept the Báb strictly confined and allowed no visitors. He had a vision of the Báb engaged in prayer outside of the prison gates, knowing that the Báb is inside. He became humble and permitted the Bábís to visit the Báb. [Bab129–31; DB245–8]

The winter the Báb spent in Máh-Kú was exceptionally cold. [DB252]

Many of the Báb's writings were revealed in this period. [GPB24–5]

Upon arriving in Qazvín, Táhirih refused her estranged husband's attempts at reconciliation and lived with her father. Her father-in-law Hájí Mullá Taqí, felt insulted and denounced the Shaykhís and Bábís. [B166; DB2736]

Mullá Husayn proceeded to Mashhad and built a `Bábíyyih', a centre for the Bábís, as instructed by Quddús. He and Quddús took up residence in it and began to teach the Bábí religion.

Bahá'u'lláh, who hosted and directed the event, rented three gardens, one for Quddús, another for Táhirih and the third for Himself. [Bab168; GPB31, 68; MF200]

The conference coincided with the removal of the Báb to Tabríz for interrogation in July. It was held near the village of Sháhrúd in Semnan province. [BBRSM23; DB292]

Táhirih was arrested and was later taken to Tihrán where she was held in the home of Mahmúd Khán, the Kalántar of Tihrán, until her martyrdom in August 1852.

Mullá Husayn left the army camp near Mashhad where he had been a guest of a brother of the Sháh. He planned to make a pilgrimage to Karbalá. While making preparations for the journey he received a Tablet from the Báb instructing him to go to Mázindarán to help Quddús, carrying a Black Standard before him. He was also instructed to wear the Báb's own green turban and to take the new name Siyyid `Alí. [Bab171; BKG50; DB324; MH174]

"When the procession reached the public square, where the execution was to take place, Quddús, this youth of only twenty-seven years, cried out, "Would that my mother were with me, and could see with her own eyes the splendour of my nuptials!" As these words were being spoken the wild multitude fell upon him, tearing him limb from limb and throwing the scattered pieces into a fire which they had kindled for that purpose. Another account states that the Sa'ídu'l-'Ulamá had himself cut of Quddús' ears and struck him on the head with an axe." [TtP92]

On the subject of the successor to the Báb the Guardian states:

A successor or vicegerent the Báb never named, an interpreter of His teachings He refrained from appointing. So transparently clear were His references to the Promised One, so brief was to be the duration of His own Dispensation, that neither the one nor the other was deemed necessary. All He did was, according to the testimony of 'Abdu'l-Bahá in "A Traveller's Narrative," to nominate, on the advice of Bahá'u'lláh and of another disciple, Mírzá Ya˙yá, who would act solely as a figure-head pending the manifestation of the Promised One, thus enabling Bahá'u'lláh to promote, in relative security, the Cause so dear to His heart. [GPB28—29]

.He has also referred to him as "titular head" and "a mere figurehead". [GPB90]
