Heartland and Rimland Theories:
-This theory was developed in 1904 by Halford J MacKinder. -His geopolitical theory argued that political power depended on geographical location. More specifically, his theory can be explained with the following sequence: -1) He who rules inland Europe ( “Heartland) à rules Eastern Europe-2) He who rules inland Europe ( “Heartland”) à rules Europe, Asia, and Africa ( “World Island”) -3) He who rules Europe, Asia, Africa ( “World Island”) à rules the World ( “World Domination”)
-At the time when this theory was developed, new technologies caused society to look at geography and military strategies in a new light. For instance, the railroads, a relatively new technology, meant that the army was no longer dependent on the navy for transportation. The railroad was the new and more efficient means of transportation that shifted the focus away from the coast, ( “Rimland”) and allowed armies to travel all throughout the land rather than solely on the sea. Military attacks by sea remained a serious threat, however, and for this reason MacKinder further believed that greater political power lay in the Heartland as it was easier to defend than a coastal territory.
-MacKinder’s theory was poplar and well-received. Nazi Germany, for example, used this theory to advance the idea of Nazi World Domination.
-As for if this theory is applicable in today’s world, I would say that it is not applicable because power lays in the hands of the countries that have the most technology such as China, rather than the country that has the best geographical location. The theory also helps us understand MacKinder’s time, and the importance that geographical location had.
