Pre-modern long-distance trade was fraught with risks which often created conflicts of interest. The ensuing disputes and the ways the actors involved dealt with them belong to the field of conflict management. How did victims of maritime conflicts claim compensation? How did individual actors and public institutions negotiate disputes which transcended jurisdictional boundaries? What strategies, arrangements and agreements could contribute to achieve the resolution of such conflicts, and to what effect? These and other questions have mainly been studied separately for the Mediterranean and Atlantic regions. Here, the two seascapes are connected, allowing for a comparative long-term perspective. The different contributions enhance our understanding in the complexity of various approaches to conflict management.
