Security as a Dependent and Conflicting Concept

Here based on a descriptive-analytic method, the author tries to examine conceptual transformation of security and evolutionary movement of security studies from the end of Second World War to post cold war era, and the elements that affected it. In theoretical sphere, despite practical sphere, security studies as a sub-discipline in IR, manifested after Second World War for the first time. Decadence of idealist thoughts between two world wars, dominance of realism in IR studies and beginning of cold-war have made a situation for realistic presuppositions to be dominant in security studies. This concept of security remained as a main approach in security studies until the end of cold war. In post cold war era security studies has been influenced by two factors: international changes because of Soviet collapse, and extensive transnational changes because of globalization. Then, two theoretical trends have been shaped; for example, third world school, critical school, critical theory and Copenhagen school. Based on the new theories, in contrast to positivist approaches, security has no stable, given indication, but is a dependent concept with a fluid and conflicting nature
