This special issue of Contemporary South Asia seeks to capture the diversity and situatedness of the caste experience and deepen our understanding of caste dynamics and lives in the twenty-first century. In this Introduction, we highlight the continuing salience of caste, offer an overview of theoretical understandings of caste and foreground the importance of analysing caste in the present as a dynamic form of human relations, rather than a remnant of tradition. Following on from this, we highlight the increasingly global spread of caste and reflect on what happens to castebased social relations when they traverse continents. In conclusion, we introduce the papers that make up this special issue. Taken together, they speak to changes in attitudes towards caste, but also the persistence of caste-based identities and dynamics in India and Britain. Even though the papers presented in this special issue work with the assumption of caste being a reality in and among the Indians, caste-like status hierarchies have existed in most, if not all, societies, and they continue to persist and intersect with other forms of differences/inequalities.
