Before 1815, there had been no global world power. Today in the 21st century we have become used to living with a single dominant power. We are so used to this fact that no one questions it. It is possible that ancient China might have decided to become such a power; she had the technical shipbuilding knowledge, but she showed no interest. A world power needed a superior military force, a vibrant economy to support its military might, a navy able to travel across the world, and some purpose that encompassed the world.

The transformation from an ancient society towards an industrial urban capitalist world has nearly always been a revolutionary process which has torn society apart. The almost complete breakdown of societies in the multi-layered wars between the 1780s and 1815, and then from 1914 to 1945, reflect these long-term processes at work. At the end of both periods, not only was the world a very different place with many millions of people dead, but many of the necessary conditions towards the industrial urban capitalist world had also been established.
