The Babis took up arms

Algar sees the Babi movement as a heresy of Shi‘i origin that sought to overthrow orthodoxy by force. He maintains that the Babi rebellion began in the summer of 1848, when Mulla Husayn-i-Bushrw’i, the Bab’s most renowned disciple, marched toward Mazandaran at the head of a band of Babis. MacEoin has proposed the view that “between 1847 and 1850, following the Bab’s announcement that he himself was the Qa’im, his followers took up arms to begin the last crusade or share in the messianic woes in the hope of hastening the final restitution of things.”
