Medieval maritime diplomacy: the case of Norwegian–Scottish relations,ca. 1266–1468/69

Abstract

In 1266, Norway and Scotland entered into an agreement aimed at pacifying a long tradition of competition over control of the islands and waterways along Scotland’s seaboards. This paper examines how the two kingdoms developed diplomatic strategies aimed at regulating social, economic and political developments along their common maritime frontier, and seeks to show how effective diplomacy was in ensuring long-term peace and stability in the region throughout the Late Middle Ages. It focuses on three issues which were addressed more explicitly in Norwegian–Scottish accords: first, the question of dominion over the islands around Scotland’s seaboards; second, the question of mobility to and from those islands; and third, the question of how to protect and limit the threat of piracy in and around those islands. Although largely unprecedented in a Northern European context, this case reveals emerging concepts and strategies of maritime sovereignty in the Late Middle Ages.
