Abstract:-The period from the later part of the nineteenth century to the early twentieth century is a crucial phase of Assam history. From the advent of the colonial rule till the growth of the nationalistic aspirations, a new society with indications of modernity was gradually emerging. The emerging Assamese middle-class of that time was capable of adapting themselves to the changing situations. The new professional requirements ushered a change in their life style. Along with the material changes, equally significant was the change of attitude. It was rightly reflected in their personal life and family relations. Account of family life is a notable part of an autobiography. For social history, an autobiography is a valuable site of research as an expression of the world-view of a person or a generation. This paper is an attempt to explore that aspect of social history of Assam primarily from the autobiographies of four memorable lives who were individually and collectively interesting characters and were actively concerned with the issues of this epoch making age.
