The transplantation of the caste system into the colonial diaspora represents a complex process of adaptation, negotiation, and transformation shaped by the conditions of migration, colonial policies, and intercultural contact. When large numbers of Indians migrated as indentured laborers, traders, and professionals to regions such as the Caribbean, Africa, Southeast Asia, and Fiji during the nineteenth and early twentieth centuries, they carried with them social structures rooted in caste, even though these structures were significantly reconfigured in the new environments. In the early phase of migration, particularly under the indenture system, the rigidities of caste were challenged by the conditions of the voyage and plantation life. The crossing of the seas, often referred to as “kala pani,” traditionally implied loss of caste status in orthodox Hindu belief. Despite this, migrants continued to maintain a sense of caste identity, though often in a diluted or symbolic form. On ships and plantations, individuals from different caste backgrounds were forced into close proximity, sharing food, water, and living spaces, which weakened strict notions of purity and pollution. The practical necessities of survival often overrode ritual restrictions, leading to the emergence of a more flexible and situational caste consciousness. However, caste did not disappear entirely; instead, it adapted to new socio-economic contexts. In many colonial settings, caste identities became markers of cultural memory rather than rigid hierarchies governing everyday interactions. For example, Brahmins sometimes retained a degree of ritual authority, performing religious ceremonies and maintaining temples, but their dominance was often less pronounced than in India. Similarly, artisan and service castes continued certain occupational roles, though the plantation economy largely homogenized labor into a common category of “coolie” workers, thereby reducing occupational specialization linked to caste. The colonial state also played a role in shaping caste dynamics in the diaspora. Administrative practices such as census classifications and labor recruitment sometimes reinforced caste identities by recording them as fixed categories. Recruiters often selected laborers from specific regions and communities, inadvertently transplanting localized caste compositions into overseas colonies. At the same time, colonial policies did not actively sustain caste hierarchies in the way traditional Indian society did, allowing for greater social mobility and the erosion of rigid boundaries. In many cases, economic success, education, and access to colonial institutions became more important determinants of status than caste origin. Religious institutions served as key sites for the reconstitution
