Book excerpt: In the Name of the Battle against Piracy discusses antipiracy campaigns in Europe and Asia in the 16th-19th centuries. Nine contributors argue how important antipiracy campaigns were for the establishment of a (colonial) state, because piracy was a threat not only to maritime commerce, but also to its sovereignty. 'Battle against piracy' offered a good reason for a state to claim its authority as the sole protector of people, and to establish peace, order, and sovereignty. In fact, as the contributors explain, the story was not that simple, because states sometimes attempted to make economic and political use of piracy, while private interests were strongly involved in antipiracy politics. State formation processes were not clearly separated from non-state elements.
