The concept of Geopolitics which in the course of 20 th century has gone through different phases, can be studied in distinct periods to signify the link between geography and politics. Efforts have been made by theorists in these distinct periods to explain changes in the world order structure, and while proposing the effective factors of changes in the world order, they also analyzie the upcoming orientations of this order. In these distinct periods, the traditional concept model of geopolitics as part of imperialistic knowledge dealing with relation between land and politics, was studied by geopoliticians. The relation between geopolitics concept and the ruins Caused by the world wars, led to the nonuse of this term for one or two decades. The outcome of this decline was the seperation of political geography from geopolitics. During the cold war era, geopolitics was influenced by challenges of the two super powers. Following the advent of a new viewpoint as critical geopolitics in 1975, the concept of geopolitics became more susceptible to revival. With critical geopolitics, emphasis has been put on the formation of foreign policy rather than on finding out the impressions of geographical factors. This article intends to study the manner of entering to critical geopolitics arena with a historical - analytical approach.
