The history of a society might be viewed as the process by which a community attempts to affirm, through religious and political structures and values, the legitimization of its power and authority. Successive efforts to weave new patterns of legtimization might therefore define the process of change in that society. South India and Sri Lanka stand out in the degree to which they exemplify this historical process of shaping and transforming the mechanisms of the social order. This book examines the process these two areas followed.
