Classical Political Geography has as its precursor the German geographer Friedrich Ratzel, who laid the scientific and systematizing bases for this science with the publication, in 1897, of the work Political Geography. For Ratzel, the strength of the State was closely linked to space - in its shape, extent, relief, climate and availability of natural resources -, to its position - social relations established between the State and its circulating environment at the national and international level - and, finally, to the sense (or spirit) of the people, which represented the strength of that determined people in relation to another. These ideas, understood in a simplistic and distorted way, would be known as "geographic determinism". (Geographical determinism, however, occurs when natural elements are given the sole role in defining the constitutive aspects of societies.)
