The start of this century has seen Hindu nationalism emerge as a more dominant force than ever before. Hindutva is also evolving and shifting in new, surprising, and significant ways, requiring us to reassess and reframe prevailing understandings. This special issue seeks to identify and understand the ways in which Hindu nationalism increasingly permeates into new spaces: organisational, territorial, conceptual, rhetorical. It develops and expands on the idea of ‘neo-Hindutva’: ‘idiosyncratic expressions of Hindu nationalism which operate outside [or on the peripheries] of the institutional and ideological framework of the Sangh Parivar’ [Anderson, Edward. 2015. “‘Neo-Hindutva’: The Asia House M.F. Husain Campaign and the Mainstreaming of Hindu Nationalist Rhetoric in Britain.” Contemporary South Asia 23 (1): 45–66]. The scope of the articles in the special issue reflects the diversity of contemporary Hindutva, which appears simultaneously brazen but concealed, nebulous and mainstreamed, militant yet normalised. They cover a wide range of topics and places in which we can locate new forms of Hindu nationalism: courts of law, the Northeast, the diaspora, Adivasi communities, and the internet. The special issue also includes an in-depth interview with Christophe Jaffrelot and a postscript by Deepa Reddy. These interventions, we hope, go some way to helping us make sense of contemporary Hindutva.
