Why did the first civilizations emerge when and where they did? How did Islam become a unifying force in the world of its birth? What enabled the West to project its goods and power around the world from the fifteenth century on? Why was agriculture invented seven times and the Internet just once?

In a spirited contribution to the quickening discussion of world-historical questions such as these, J. R. and William H. McNeill explore the webs that have drawn humans together in patterns of interaction and exchange, cooperation and competition, since the beginning. Whether small or large, loose or dense, these webs have provided the medium for the movement of ideas, goods, power, and money within and across cultures, societies, and nations. Avoiding any determinism, environmental or cultural, the McNeills give us a synthesizing picture of the big patterns of world history in a rich, open-ended, concise account.
