The Theoretical Concept of Geopolitics in International Relations and Global Politics
By Dr. Vladislav B. Sotirovic
“Who rules East Europe commands the Heartland;
Who rules the Heartland commands the World Island;
Who controls the World Island commands the World”
(Sir Halford John Mackinder, 1919)
The term geopolitics was first used by the Swedish political scientist Rudolf Kjellén (1864−1922) in 1899, but the term did not become popular in academic circles until it became used in the early 20th century by British geographer and strategist Halford Mackinder.
