Navies in Northern Waters is a collection of articles covering the roles played by the secondary navies of northern European powers and the United States within the maritime balance of power. The contributions covering the 18th and 19th centuries focus on their relations with each other as they sought to create a counterweight to the dominant naval power of Britain. The inter-war years are treated from the perspectives of international disarmament efforts within the framework of collective security, and the subsequent naval rivalry in the Baltic area in the years leading up to the Second World War. For the post-1945 period, the contributions concentrate on superpower rivalry in northern waters during the Cold War, the changing aspects of security policy since the collapse of the Soviet Union and the particular challenges facing small coastal states policing extensive waters of increasing economic importance.
