 Before its birth as a full association the SNBA was one of the four Pastoral Circles under the Central Baptist Association.As churches grew rapidly with more new believers everywhere in the state, the Annual Assembly Session of Tripura Baptist Christian Union which was held in Subhash Nagar (North Tripura) on 23–26 February 1989 passed resolution that the Circles (e.g., South, Udaipur, Saisawm Sazai, and Sadar North) be given the full status of Associations.And it was how the Sadar North Baptist Association was established as an Association in the month of February 1989.
