Which geographer put forward the "Eurocentrism"?

Cohen is an American geographer. He put forward his "multipolar world" model in the book "Geography and Politics of a Divided World" published in 1973, which reflected the geopolitical situation of the world.

First of all, he believes that the world does not have the unity of strategic space like the geocentric continental margin theory, but is actually a divided world. He divided the world into two types of regions. The first level is worldwide, which is called geo-strategic area. The second level is regional, called geopolitical zone. The first level is divided into two regions according to strategic characteristics: the world of maritime trade and the world of Eurasia. The second level is to divide its geopolitical regions according to the relative consistency of culture, economy and politics.

1982, Cohen made appropriate modifications to his model, first emphasizing the multipolarization of the United States, the Soviet Union, Western Europe, Japan and China, and becoming an important geopolitical region in the world. Secondly, it has become the third fault zone in sub-Saharan Africa. Third, India, Brazil and Nigeria have become regional powers, playing an important role in the surrounding areas.

Cohen revised his model again at 199 1 according to the situation after the disintegration of the Soviet Union and the drastic changes in Eastern Europe. He divided eastern Europe into the land center and the passage area of the main body of Europe, leaving only the Middle East as a fault zone. 5. brzezinski's Trans-Eurasian Security System
