In the course of their disciplinary consolidation during the 19th and 20th centuries, the social sciences came increasingly to be less historically orientated. Analogously, global history became increasingly a marginal concern for professional historical scholarship. At the present juncture, however, there is a coincidence of a rethinking of the formation of modernity in cultural terms and the need to locate European modernity in a global context. Social theory must be able to provide an account of global historical developments that is (...) less constrained and biased than modernization theory, even in the new garb of globalization studies, but significantly more elaborate in conceptual terms than current contributions to global history. A rethinking of the formation of modernity has already contributed to a greater appreciation of processes of cultural and ideational transformations. It has also suggested new ways of studying institutional change. It must, however, also be able to locate the specific European trajectory in a global context. The core element in such a research programme is the analysis of three major periods of global cultural crystallization, namely the Axial Age, the ecumenical renaissance, and the formation of modernity. The rationale and the contours of this research programme are outlined. (shrink)
