The Diamond Age

Society in The Diamond Age is dominated by a number of phyles, also sometimes called tribes. Phyles are groups of people often distinguished by shared values, similar ethnic heritage, a common religion, or other cultural similarities. In the extremely globalized future depicted in the novel, these cultural divisions have largely supplanted the system of nation-states that divides the world today. Cities in The Diamond Age appear divided into sovereign enclaves affiliated or belonging to different phyles within a single metropolis. Most phyles depicted in the novel have a global scope of sovereignty, and maintain segregated enclaves in or near many cities throughout the world.

The phyles coexist much like historical nation-states under a system of justice and mutual protection, known as the Common Economic Protocol (CEP). The rules of the CEP are intended to provide for the co-existence of, and peaceful economic activity between, phyles with potentially very different values. The CEP is concerned particularly with upholding rights to personal property, being shown to provide particularly harsh punishment for harming the economic capability of another person. The role of the CEP in the world of the novel could be seen in comparison with the roles of real-life international organizations such as the United Nations and the International Monetary Fund.
