The "Thombos" are a rather unique collection of eighteenth-century land and population registers detailing the lives lived, lands held, and labour provided by tens of thousands of people inhabiting the coastal regions of Sri Lanka that were colonised by the Dutch East India Company. Turning this archive inside out by highlighting both the indigenous and colonial roots of this administrative system, Luc Bulten presents a gateway into everyday social realities surrounding caste, conjugality, (forced) work, and land tenure. In doing so, he demonstrates how both European expansionism and local agency reciprocally affected the ways such social realities were shaped.
