Locarno: a democratic peace?

Explanations for the lack of war between democracies are many, various and contested. The main thrust of research is quantitative but there is also a growing literature of case studies. Such studies can throw light on the issues by showing in particular contexts the complex interaction of different factors, those both consistent and inconsistent with democratic peace theory. The detente in the 1920s between France and Germany offers an interesting example for several reasons. Both were democracies but one (Germany) was still undergoing democratisation. In addition, neither was content with the status quo, the distribution of power between them was unstable and that instability was not resolved by an over-arching alliance system (such as NATO) or strong international institutions. A complex interaction resulted between France's security dilemma, the German Republic's need for foreign policy success and the democratic values of political leaders on both sides.
