Book excerpt: This volume explores the issues of taking, using and being hostages in the Middle Ages. It brings together recent research in the areas of hostages and hostageships, looking at the act of hostage-taking and the hostages themselves through the lenses of political and social history. Building upon previous work, this volume in particular critically examines not only the situations of hostages and hostageships but also the broader social and political context of each situation, developing a more complete picture of the phenomenon.
