Book excerpt: We live in a rapidly changing world in which politics is becoming both more and less predictable at the same time: this makes political geography a particularly exciting topic to study. To make sense of the continuities and disruptions within this political world requires a strongly focused yet flexible text. This new (sixth) edition of Peter Taylor’s Political Geography proves itself fit for the task of coping with a frequently and rapidly changing geo-political landscape. Co-authored again with Colin Flint, it retains the intellectual clarity, rigour and vision of previous editions, based upon its world-systems approach. Reflecting the backdrop of the current global climate, this is the Empire, globalization and climate change edition in which global political change is being driven by three related processes: the role of cities in economic and political networks; the problems facing territorially based notions of democratic politics and citizenship, and the ongoing spectre of war. This sixth edition remains a core text for students of political geography, geopolitics, international relations and political science, as well as more broadly across human geography and the social sciences.
