This paper is the last in our trilogy on Twenty-First Century Historiography. It attempts to bring all our endeavours to their logical culmination and as such may be construed to be our apotheosis in this regard. The first paper proposed a basic approach for Historiography in the Twenty-first Century and laid out the basic objectives of Twenty-first Century Historiography. The second paper laid out the core principles of Twenty-first Century Historiography, and these were seen a necessary adjunct for the accomplishment of the objectives of Twenty-first Century Historiography as defined in the first paper. In this paper, we introduce Anthropological Historiography as an integral, though not core component of Twenty-first Century Historiography and lay down is basic tenets and objectives. We also delineate the role that we expect will be played by Anthropological Historiography in the attainment of long-term Anthropological goals and objectives, and in promoting human welfare and wellbeing in general. Anthropological Historiography, with its myriad and multiple interfaces with other sciences is also expected to play a major role in promoting a scientific temper among the laity and the general public and trigger shifts in individual and societal orientations in due course by countering popular perceptions on many issues that impact their daily lives and making outdated and popular paradigms and ideologies redundant. We expect that Anthropological Historiography will play a major role in marginalizing fringe movements besides leading to an enhanced understanding of various aspects of science, history and ethnology among the population and ushering in intellectual movements where such movements are long overdue, and very indirectly leading to a quantum increase in scientific endeavours. We also believe that Anthropological Historiography should be taught as a specialized sub-discipline chiefly targeted towards higher grade students, or students pursuing advanced courses, and should be pursued not by general historians, but by specialized Anthropological Historians.
