This study has aimed to examine the rapid change in the issue of the Swedish conscription. In the year 2009 the government decided to abandon the national conscription and replace it with a professional army. However, in 2014 the minister of defence announced that the government would investigate the possibilities of bringing the national conscription back. John Kingdons Multiple Stream Theory aims to reveal the process of “knowing when an idea ́s time has come”, and has been applied to several policyprocesses spanning over a longer time-period. This study has a twofold purpose: to examine whether the theory can be applied to a case of rapid policy change and whether it can help explain a case of rapid change in existing policy. The method chosen in this study is processtracing through a qualitative method. The study concludes that the theory is indeed applicable to a case of rapid policy change and that the content and nature of the problemstream (what appears to be the problem) can be one explanation to rapid change in existing policy.
