Manav Dharma Sabha was one of the earliest socio-religious reform movements in Gujarat and British India. It was founded on 22 June 1844 in Surat by Mehtaji Durgaram Manchharam, Dadoba Panderung Tarkhadkar and a few others. The goals of the Sabha were to expose the hypocritical arts present in Christian, Muslim and Hindu religions. It had a very short life span and ceased to exist as Dadoba left for Bombay in 1846 and Durgaram left for Rajkot in 1852. It acted as a secret society and is believed that the revelation of its existence compounded to its demise.
