This book demonstrates that geohistory is a more effective concept than geopolitics in understanding inter-state relations, at a time of considerable confusion in world affairs, and that Francesco Guicciardini's thoughts are an efficient medium to demonstrate not only the inadequacies of geopolitics, but that a geohistorical approach can be a more responsible way of understanding international affairs. The book introduces a fresh approach, based on the individual, on which corporate characteristics and behaviour depend, often in the shape of state interests, which are unable on their own to predict actions driven by human behaviour. The book shows how show mainstream international relations theories are stuck in paradigms, inadequate in explaining why world politics is moving in a direction that nobody could predict even a decade ago. It shows how ideology can blur clear understanding. In short, it represents a new and intellectually refreshing approach and method in understanding, and tackling, the vagaries of relations between states.
