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.[17] 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 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.[18]
