Original: In 1863, at the time of his banishment from Baghdad to Constantinople, BahÃ 'u'll Ã h 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 BÃ bÃ s who did not recognize BahÃ' u'll Ã h's claim.
Simplified: Followers of this religion call themselves BahÃ 'Ã s/O. The name BahÃ' u'll Ã h is Arabic for "The Glory of God".
