Raja Ram Mohan Roy formed the Brahmo Samaj which played an important role in forbidding idol worship and preaching worship of one God.
Brahmo Samaj split into two different organisations in 1866. Debendranath’s organisation came to be known as Adi Brahmo Samaj.
Furdunji Naoroji founded the Rahnumai Mazdayasnan Sabha which worked for Parsi reforms in 1851 and the Rast Gofter, an Anglo-Gujarati newspaper to voice his opinion.
