Offering editorial commentary and interpretation while presenting wide-ranging sources from the early modern period to the present day, the book chronicles how British statecraft has functioned in the Baltic as a geopolitical space. British Statecraft and the Baltic: A Documentary History chronicles how British statecraft has functioned in the Baltic as a geopolitical space and shows how Britain's relationship with the region has shaped the evolution of British political economy. Bringing together a carefully selected variety of variety of sources, it begins in the early modern period, with the rise in diplomatic and commercial engagement with the Baltic Sea region and continues to the present day, engaging with the consequences of Brexit and increased Russian hostility. Britain's relationship with the Baltic has always been defined by its proximity firstly to the European geopolitical struggle centred on Germany, and secondly to a 'Eurasian hinterland' that has long provided Europe with crucial natural resources, from the grain, potash and naval stores that passed through the Danish straights, to oil and natural gas, and that gives Russia huge influence over the region. In light of these proximities, British statecraft in the Baltic has been fundamentally shaped by the challenges of preventing imperialism in Europe. From the role of neutrality in economic coercion to the question of whether, and how, Britain should commit to defending the sovereignty of European states, the Baltic is where Britain has always wrestled most acutely with the meaning of sovereignty. Outside the European Union, Britain's relationship not only with 'Europe' as a single, increasingly integrated geopolitical area, but with different European geopolitical spaces and states has become even more important. The Baltic remains one of the key areas of geopolitical interest for Britain today, with British troops deployed to Estonia and Poland, and longstanding commercial and political relationships with states across the region established. The authors take a clear view: that Britain must continue to commit to its commitments under Article 5 to preserve liberty and democracy at home. However, by engaging with the historical documents that chart British statecraft over 300 years, British Statecraft and the Baltic allows specialist and non-specialist readers alike to form their own understanding of British statecraft.
