What were the major developments in thinking about Dutch empire from the early modern period to the twenty-first century? What moral, political, legal and economic arguments have been put forth to justify, criticize or reform empire? How and under what circumstances did these visions and arguments change or remain the same? This article outlines a research agenda that addresses these questions. It argues for an approach that includes a long-term perspective from the early modern period to the postcolonial situation, which sees ‘Dutch' history broadly, moving beyond national borders, and instead explicitly informed by influences and actors from across the globe. This implies a transnational and transimperial approach that can highlight these global connections as well as tensions; and finally, an approach that understands intellectual history as going beyond the big names of systemic thinkers, and includes visions of empire as negotiated in (day-to-day) practice.
