History shows how relatively small naval forces can have a disproportionately large impact on global events. This collection, which adopts an interdisciplinary approach drawing on the best new research from the fields of international relations, security studies, strategic studies and maritime history, addresses the roles and activities of small navies in the past and the present, and investigates the relationship of such navies with non-governmental institutions in pursuit of broader maritime goals, be they political, financial or environmental.
