This article argues that Britain's standing as a maritime nation must be considered if we are to fully understand the objectives behind British foreign policy in the late eighteenth and early nineteenth centuries. It focuses on one of the most important challenges successive British governments faced during this period; the need to secure shipbuilding resources. Both British economic prosperity and national security depended upon the continued supply of naval stores. These resources could only be procured from the Baltic region, which meant the region took on a crucial strategic importance for policy-makers. This article will focus on Britain's relationship with the Baltic between 1780 and 1815 tracing Britain's sensitivity to the changing political environment in Sweden, Denmark, Prussia, and particularly Russia, and outlining how this came to dictate foreign policy. Britain hoped to rely on diplomacy and economic interdependence to maintain the movement of naval stores from the Baltic; however intransigence from the Baltic powers forced Britain to resort to military measures on three occasions between 1800 and 1815, such was the importance of these shipbuilding resources.
