Contemporary and historical narrations of the Dutch relationship to the sea involve tales of maritime heroism and prowess. At the same time, the colonial-racial underpinnings of Dutch expansion overseas remain invisible. Conventional land-based accounts of Dutch empire and colonialism simply mention the ocean in passing, often as a route between colony and metropole. In Maritime Imagination, I develop an oceanic framework for the study of Dutch imperialism and its aftermath. Following a turn to the ocean in recent humanities and social science research, I ask what a turn to the ocean might teach us about Dutch imperial imaginaries, cultures, and politics. Tracing the movements of Dutch ships and stories of Dutch maritime prowess across oceans, this project strengthens the conceptual and theoretical framework of Ocean, Colonial and Globalization Studies by highlighting the formative role of Dutch maritime imagination and its impact in shaping colonial, imperial, racial, gendered, and capitalist discourses. The aim is to improve our understanding of the political, socio-economic and cultural role of the ocean in the transportation of cultures, people, goods, and legal regimes across Dutch empire. It maps and analyzes the shifting legal, cultural, socio-economic and political discourses of the Dutch maritime world (1600 - present) to better understand its impact on state and empire formation. Constructing a cultural oceanography of Dutch empire, the project shifts the classic focus on land to the importance of the sea. This shift to the ocean expands pressing public debates in The Netherlands, Europe and elsewhere on revisiting, revising, researching, and representing colonial histories in a globalized present. By collaborating with the cultural and academic sector, I develop new ways of communicating academic research to a broader audience through public events and interdisciplinary curriculum development. With this project, I have shown the importance of turning to the ocean as a framework and methodology for the study of Dutch imperialism and its aftermath. In conclusion, Dutch maritime imagination has deeply impacted European imperialist and legal thought. From racialised discourses of trade and navigation to contemporary imaginaries of climate catastrophe and rising sea levels, Dutch maritime imagination continues to impact how we address contemporary societal and environmental challenges.
