Today, energy security is an important domestic and foreign policy matter and states are looking for alternative energy sources more vigorously than ever before. Using the “Heartland Theory” of British geographer Halford Mackinder to evaluate the theoretical claims that the convergence of foreign policy and energy security is driving competition for influence in the world, we examine the “competition” among the powerful political actors in the Caspian. Our findings suggest that the need for a continued source of energy has shifted national energy security policies from purely military affairs to prioritizing stable oil markets and has created potential roles, especially for powerful regional actors. After our review of the historical and present competition over Caspian energy sources, we analyze the effects of growing internationalization and securitization of global energy issues for Turkey and the possible implications of different foreign policy options Turkey is likely to pursue in the region.
