From Pax Americana to a Multiplex World: The Changing Architecture of Global Cooperation

Cohen Center 214

The shifting pattern of global leadership is examined using a new concept for describing world order – Multiplexity. Our analysis shows the world order changing from British leadership (Pax Britannica) to United States leadership (Pax Americana), to what we call a “Multiplex” order, or a more decentered, pluralistically led world. To do this we use a new dataset composed of post-World War II treaties to measure interaction density and proximity allowing us to analyze leadership as a key driver of world order and thus to draw conclusions about it.  Our analysis shows a decline in the relative importance of great powers, an increase in the relative leadership and power of middle and small powers, and the significance of clusters of cooperation among nations that are not geographically close.
