The diplomacy of the Congress Vienna and the modern geopolitical interests of the great powers

We can define geopolitics as a field of study that depicts the political interests, natural resources and strategic dominance between nations, aimed to pursue their own or collective interests. The aim of this paper is to give a survey of the foreign policy of the great powers in the past 200 years, starting from the Vienna Congress until today. A comparison of the foreign policies of great powers clearly shows that geopolitical interests are constant and never change. While in the 19th century geopolitical interests were focused on geostrategic territories and the formation of great and powerful European empires, today, geopolitical interests have completely shifted, while big players are seeking to dominate energy resources all around the
globe.
