As mentioned, the Adi Dharma founders were regularly tainted and scandalised by orthodoxy as Pirali Brahmin and defamed as being officially banned from entering temples like Jaganath Temple (Puri) by Govt regulations of 1807.
Consequently the Adi Brahmos then set up their own faith called Adi Brahma Sabha in 1828/1830 by Trust deed of Brahmo Sabha and codified their religion as Adi Brahma Dharma published from 1848. The founders of this Brahmo religion were foremost reformers for nationalism, equality, secularism and education which now stand enshrined in the Constitution of India as Fundamental Rights. These founding fathers of Adi Dharma believed then that Hinduism was thoroughly corrupted and debased and that strong Law (ie. Dharma) of first Moslems and then English Rulers could cleanse India from these evils. For their associations with the Rulers of the times, they were ostracised and barred from orthodox Hindu society but were amply compensated by "being so weighed down in honours by the British that they forgot all the radicalism of their youth." It was Dwarkanath Tagore alone who could publicly lambast an English Magistrate Abercrombie Dick on the emergence of servile mai-baap (great lord) ruling culture of 19th cent. Bengal as follows:-
Previously in 1829 Dwarkanath and Prasanna Coomar had founded the Landholders (Zamindars) Association which in its variants went on to play such role in modern India's development. The first major success of this Zamindari Sabha was arraigning the East India Company forces against Titumir a Muslim extortionist of zamindars (or jehadi freedom fighter) at Nadia in November 1831.
