 In 1863, at the time of his banishment from Baghdad to Constantinople, Baháʼu'lláh declared his claim to a divine mission to his family and followers.Tensions then grew between him and Subh-i-Azal, the appointed leader of the Bábís who did not recognize Baháʼu'lláh's claim.Throughout the rest of his life Baháʼu'lláh gained the allegiance of most of the Bábís, who came to be known as Baháʼís.
