On the Size and Configuration of Viking Fleets in the Diaspora

Abstract This article re‐examines the question of viking fleet sizes across the western and southern diaspora, challenging long‐standing assumptions of exaggeration in medieval accounts. While fewer scholars today subscribe to such assumptions in relation to some parts of the viking diaspora, the idea that sources exaggerate the size of viking armies still holds sway amongst scholars dealing with other regions, such as medieval Iberia. Through a comparative analysis of texts with varied origins, this article identifies a striking consistency in recorded fleet numbers, suggesting that large fleets were common across Europe. The article also explores fleet composition, highlighting evidence for significant numbers of cargo vessels. By integrating northern and southern historiographical traditions, it proposes a more interconnected understanding of viking activity across the Western Atlantic–Mediterranean world.
