In the event, Friedrich Ratzel's metaphoric concept of society as an organism—which grows and shrinks in logical relation to its Lebensraum (habitat)—proved especially influential upon the Swedish political scientist and conservative politician Johan Rudolf Kjellén (1864–1922) who interpreted that biological metaphor as a geopolitical natural-law.[18] In the political monograph Schweden (1917; Sweden), Kjellén coined the terms geopolitik (the conditions and problems of a state that arise from its geographic territory), œcopolitik (the economic factors that affect the power of the state), and demopolitik (the social problems that arise from the racial composition of the state) to explain the political particulars to be considered for the successful administration and governing of a state. Moreover, he had a great intellectual influence upon the politics of Imperial Germany, especially with Staten som livsform (1916; The State as a Life-form) an earlier political-science book read by the society of Imperial Germany, for whom the concept of geopolitik acquired an ideological definition unlike the original, human-geography definition.[19] Kjellén's geopolitical interpretation of the Lebensraum concept was adopted, expanded, and adapted to the politics of Germany by publicists of imperialism such as the militarist General Friedrich von Bernhardi (1849–1930) and the political geographer and proponent of geopolitics Karl Haushofer (1869–1946). In Deutschland und der Nächste Krieg (1911; Germany and the Next War), General von Bernhardi developed Friedrich Ratzel's Lebensraum concept as a racial struggle for living space; explicitly identified Eastern Europe as the source of a new, national habitat for the German people; and said that the next war would be expressly for acquiring Lebensraum—all in fulfillment of the "biological necessity" to protect German racial supremacy. That vanquishing the Slavic and the Latin races was necessary, because "without war, inferior or decaying races would easily choke the growth of healthy, budding elements" of the German race—thus, the war for Lebensraum was a necessary means of defending Germany against cultural stagnation and the racial degeneracy of miscegenation.[20]
