Who came up with the theory of the heart of the continent theory?

Mackinder, a British geographer.

The Heart of the Continent theory, also known as the Heart of the Continent theory, is a doctrine that analyzes international political strategy on the basis of geographic location, with the division of geopolitical zones as the main content.

The Heart of the Continent theory was put forward by the British geographer Mackinder in 1904, and the theory was developed in 1919 to put forward the global point of view of the world's political strategy.

The continental heart theory was inherited by geopolitical scholars such as K. Haushofer after the 1930s, and combined with other theories such as the organic theory of the state, it became the theoretical basis for the military hegemony and chauvinism to promote the territorial expansion policy and the decision-making of international political strategy.
