Since the dawn of history tribal people have practised self-sustainable agricultural and allied agricultural activities. Prior to the introduction of monetary & market- based economy by the Britishers in Assam, the tribal people of the region were accustomed to bartered system of economy. The entry of the tribal people of North East India including Assam into commercial activities has been a slow and steady process, which restricted their economic growth parameter within specific limits. But, over last few decades the tribal people appear to catch the vibes of commercial activities contributing significantly to their socio-economic lives and living. The present paper intends to evaluate the trend of commercial activities adopted by the tribal women of Rangapara region which covers Chariduar and Rangapara Community Development Block areas of Sonitpur district of Assam. It is interesting to find that the tribal women who had long been served as housewives & agricultural fieldworkers of their male counterparts playing active roles in adopting commercial activities over last four decades. Such a role of the tribal women adversely motivated their male counterparts, too, to opt for certain other commercial activities. The work also makes an assessment on income & employment generated by the commercial activities of the tribal women in the study area.
