AP The earth and its people Chapter 2 notes
Chapter 2 New Civilizations in the Eastern and Western Hemispheres, 2200-250 B.C.E. Notes Chapter Thesis: In contrast to the river-valley civilizations of Mesopotamia, Egypt and the Indus Valley surveyed in the previous chapter, the complex societies examined in this chapter subsequently emerge in ecological conditions quite a bit more diverse, sometimes independently, sometimes under the influence of older centers. Whereas the river-valley civilizations were originally largely self-sufficient, each of the new civilizations discussed in this chapter and the next was shaped by the development of networks of long distance trade.
