This book is aimed at those with an interest in cultivating a clearer understanding of global politics. It will hopefully bring together those who are interested in the changing dynamics of the international system with those who seek to comprehend the often-bewildering pace of change in the world around them. Above all, it is aimed at those who recognise that in global politics the last page is never truly written. We therefore need a theoretical and conceptual framework in order to ground us in stormy waters. It is only through a better awareness that we can hope to offer any lasting improvement to the world we inhabit. The book is based on a popular A-Level Politics course, taken by students typically aged 16–18 in the UK’s national curriculum system and presents both as a guide to an A-Level student and/or a starting point for any reader looking to get to grips with the fundamentals of how the world works – including as preparation for embarking on an International Relations degree at university.
