The advent and expansion of trans-oceanic shipping aboard wooden, wind-powered vessels between India and Europe created uniquely onerous working conditions for the Indian seamen who volunteered to labour aboard – conditions distinct from either coastal or land-based employment in either India or Europe. Indian (and European) seamen on such vessels may have been “free labour” prior to boarding ship, but they were in many respects “unfree labour” while at sea. They were unable to change jobs, to vary the amount of labour extracted from them, to increase the compensation or necessities provided, or to quit – in short, to do much to improve their working conditions generally. They sailed for uncertainly long periods of time, confined to constricted, unhealthy spaces and limited diet, almost constantly facing the various dangers of the open sea under the virtually unavoidable, unrelenting, and unalterable hierarchic authority and often brutal physical discipline of European officers.
