Ellen Churchill Semple,
Influences of Geographic Environment
“ In history, the question of territory,—by which is meant mere area in contrast to specific geographic conditions—has constantly come to the front, because a state obviously involved land and boundaries, and assumed as its chief function the defence and extension of these. Therefore political geography developed early as an offshoot of history. Political science has often formulated its principles without regard to the geographic conditions of states, but as a matter of fact, the most fruitful political policies of nations have almost invariably had a geographic core. ”
