Book excerpt: The study of territorial politics has enjoyed a renaissance in the last thirty years. Scholars have questioned the state-centric assumptions upon which mainstream social science has been built, pointing to the territorial (re)distribution of power across and within states. This Handbook brings together leading scholars to demonstrate how territory has shaped institutional structures, public policies, elections, political parties, and identity across the world. Offering theoretical, comparative and empirical insights, this book provides a comprehensive overview of the impact of territory on modern political, economic and social life.
