THE INDIAN IMMIGRATION ARCHIVE IN MAURITIUS The complexity and richness of Mauritian studies belies the geographical smallness of this Indian Ocean country. An island of 720 square miles, named after a Dutch stadhouder, Mauritius was captured for the British Empire from the French in 1810. Within a few decades the island had been transformed into a major sugar producer and experienced an unprecedented demographic revolution as existing Creole and European populations were dwarfed by an immigrant Indian community which rapidly gained majority status. By Marina Carter The Indianization of Mauritius was a deliberate policy of the British who selected the island to be the site of "the great experiment" in the use of "free" rather than slave labour. Mauritius was chosen because it was perceived to be a new and expanding plantation economy unlike the "exhausted" West Indian sugar producers, and because of her proximity to India. Thus, Mauritius became the first British colony to be allowed to export labour under a government regulated indenture system from 1834. The indentured workers were so called because they were obliged to sign contracts of varying duration which bound them to serve for a fixed wage. Because the migration was designed to prove a viable alternative to slave labour, indenture was a system under scrutiny. As a result the entire proceedings, from recruitment, through shipping, allocation to estates and employment history was recorded. Individual data were compiled to describe and differentiate migrants, and from the 1860s photographs of Indian immigrants were taken to complete the system of control. The registers in which this bio-data was recorded are collected at the Indian Immigration Archives of the Mahatma Gandhi Institute, Mauritius. The Archive houses unique ship registers, migrant certificates and photographs relating to one of the largest of the modern Indian diasporas; these comprise migrant data recorded at the point of entry, and records of subsequent employment, and settlement patterns of Indians in Mauritius. The size, comprehensiveness, and quality of the database (circa half a million migrants) is unique. In no other territory to which Indians migrated as labourers (for example the Caribbean, South Africa and Sri Lanka) is statistical material available which can enable the historian to match individual bio-data (region, caste, age, gender) with subsequent employment and settlement records (marriage, death or return dates). The study of this material will enable us to recreate a unique picture of the transplantation of an essentially rural or `peasant' population into a plantation society. The data reveal aspects of the living and working conditions of indentured labourers (through birth and death rates) so that scholars specializing in the quantitative study of coerced labour would find much of interest in the records. Correlations between death rates and migrants' region of origin can provide new information about the epidemiological conditions of the subcontinent. In addition, the analysis of the Indian population data can provide us with an insight into the modification of traditional customs and practices in the new setting - for example, the selection of marriage partners in Mauritius by the children of immigrants entailed adaptation from the caste endogamous patterns which their parents had followed. The photographs (the collection dates from 1868) and personal data (e.g. height, family status) recorded for individual migrants can also be used to provide Indian demographers, historians, and anthropologists with a valuable new source of socio-biological information concerning the 19th century Indian populations (including tribals, Bengalis, Telegus, and Marathis as well as Tamils and Biharis who were numerically the most significant migrant groups).
