The Copenhagen School (international relations)

The Copenhagen School of security studies is a school of academic thought with its origins in international relations theorist Barry Buzan's book People, States and Fear: The National Security Problem in International Relations, first published in 1983. The Copenhagen School places particular emphasis upon the social aspects of security. Theorists associated with the school include Barry Buzan, Ole Wæver and Jaap de Wilde. Many of the school's members worked at the Copenhagen Peace Research Institute. The most prominent critic of the Copenhagen School is Bill McSweeney.

The primary book of the Copenhagen School is Security: A New Framework for Analysis, written by Buzan, Wæver and de Wilde.

Bill McSweeney is generally credited with coining the term 'Copenhagen School'.

The concept of 'sectors' concerns the different arenas where we speak of security. The list of sectors is primarily an analytical tool created to spot different dynamics. In Security: A New Framework for Analysis, the authors list the following sectors: military/state, political, societal, economic and environmental. As such, CS theory can be regarded as 'widening' traditional materialist security studies by looking at security in these 'new' sectors.

The concept of regional security complexes covers how security is clustered in geographically shaped regions. Security concerns do not travel well over distances and threats are therefore most likely to occur in the region. The security of each actor in a region interacts with the security of the other actors. There is often intense security interdependence within a region, but not between regions, which is what defines a region and what makes regional security an interesting area of study. Insulator states sometimes isolate regions, such as Afghanistan's location between the Middle East and South Asia. Insulators mark boundaries of indifference, where security dynamics stand back to back. They contrast with the traditional idea of 'buffer states' which are located at points where security dynamics are intense (e.g. Belgium between Germany and France). Regions should be regarded as mini systems where all other IR theories can be applied, such as Balance of Power, polarity, interdependence, alliance systems, etc.
