Introduction: theorising heritage for the seas.

This Introduction makes the case for a more critical engagement with oceans and the maritime within critical heritage theory. We lay out a research agenda that more consciously foregrounds aquatic domains in debates about conservation, sovereignty, governance, state power, and the politics of memory. In laying the ground for the papers that follow, we portray oceanic geographies and maritime heritage as politically and culturally charged arenas in order to argue that oceans are far from neutral or culturally egalitarian spaces and are subject to human-imposed hierarchies and competing ontologies. We scrutinize the dynamic interplay between maritime and marine realms to challenge conventional understandings of space, territory, and ownership, advocating for a reimagined approach to heritage that recognizes the ocean's pivotal role in shaping human history and culture.
