The proud and glory of India and the golden culture & tradition of Bangladesh, the maximum credit of all these goes to Buddhist religion or Buddhists. For that reason, Buddhists are the most precious wealth of this continent. Noticing the extreme loss of Buddhists and their society, some scholar, intellectuals and social-workers has come forward to rescue this loss. From them the leading roll-player was the son of Zamindar (Land-lord) Nazir Krishna Chandra Chowdhury. His daily workplace was Chittagong Judge Court. He became out-casted establishing his identity as a Buddhist in Judge Court area. The then Buddhists were included in the 36 classes of Hindu. It was forbidden and great sin to eat with Brahmins or in their place. Nazir Krishna Chandra was also sued for breaking the rules. After founding him guilty he was axed from his job and given a highest punishment. From that punishment he was rescued by a Barua Judge.Reminding this situation Krishna Chandra gave attention towards unite the whole Buddhist community under one roof to collect the recognition of the entity of the community and purifying the religion. In this view Krishna Chandra was in a search of a equal minded and wise person. At that time Sathbaria, Mahamuni Pahartali and Chakaria’s Harbang village was very advanced and wealthy. U. Gunameju Mahathero of Harbang village was the renowned Abbot of not only Rakhain but also the whole Hill Tract area. Moreover, at that time the talent monk like U. Gunameju Mahathro was also rare. So, with giving the monk the leading role with some other intellectuals Nazir Krishna Chandra Chowdhury has established “Chittagong Buddhist Association” present “Bangladesh Buddhist Association” in 1887.After partition of British India the name was changed to Pakistan Buddhist Association and later on after the independence of the country the name has been changed to Bangladesh Buddhist Association. Ven U. Gunamejo Mahathero was given the role of founder president and the general secretary was Nazir Krishna Chandra Chowdhury.
