This thesis analyzes the role of national security culture in crisis management. The use and significance of national security culture in the management of a crisis is the main concern discussed throughout this study. It is assumed that national security culture serves as the main guideline of states during crisis management and the states manage crises in line with their national security culture. This can be assessed from the responsibility undertaken by state institutions to preserve and transfer this culture. Such an assessment contributes to understanding of why national security culture is reliable in crisis management. The case of Kardak Crisis between Turkey and Greece in 1996 is examined within the framework of study purpose. The thesis traces Kardak Crisis and seeks to answer questions such as whether the Turkish national security culture was influential during the management of the crisis and if so in what ways. The case is examined in order to make the main concern of the study more clear.
