The Copenhagen School of security studies emerged at the Conflict and Peace Research Institute (COPRI) of Copenhagen. Its most prominent scholars are Barry Buzan, Ole Waever and Jaap de Wilde. They all claim that traditional methods are inadequate to describe the current security needs. Their main argument is the necessity of ‘broadening and widening’ the security agenda. In the school’s primary book, Security: A New Framework for Analysis (1998) Buzan, Waever and Wilde have built two important conceptual contributions to the study of security. Barry Buzan’s notion of sectoral analysis of security and Ole Waever’s concepts of securitization and societal security are the significant contributions of the Copenhagen School.
