I knew that I couldn’t really understand what was happening and deal with what would be coming at me unless I studied past analogous periods, which led to this study of the rises and declines of empires, their reserve currencies, and their markets. In other words, to develop an understanding of what is happening now and might happen over the next few years, I needed to study the mechanics behind similar cases in history—e.g., the 1930–45 period, the rise and fall of the Dutch and British empires, the rise and fall of Chinese dynasties, and others.
