The sea has been the site of radical changes in human lives and national histories. It has been an agent of colonial oppression but also of indigenous resistance, a site of loss, dispersal and enforced migration but also of new forms of solidarity and affective kinship. SeaChanges re-evaluates the view that history happens mainly on dry land and makes the case for a creative reinterpretation of the role of the sea: not merely as a passage from one country to the next, but a historical site deserving close study.
