On March 20, 1848, Mullá Ḥusayn-i-Bushru'i, who in 1844 had become the first person to become a follower of the Báb, visited the Báb at Maku prison, where the Báb was incarcerated.
 
Subsequent to his visit, Mullá Ḥusayn-i-Bushru'i became involved in the Bábi uprisings. Under instructions from the Báb, on July 21, 1848, Mullá Ḥusayn-i-Bushru'i unfurled a Black Standard in Mashhad, fulfilling an Islamic prophecy, and began a march with other Bábis. They were rebuffed at Barfurush and therefore made defensive fortifications at the shrine of Shaykh Tabarsí. Mullá Ḥusayn-i-Bushru'i would die at thebattle of Shaykh Tabarsí on February 2, 1849, but siege itself would last until May 10, 1849.

The Báb was later executed on July 9, 1850. Bábi uprisings would continue elsewhere in Iran, notably Neyriz and Zanjan.
