This book provides a concise and comprehensive description of all of the borders of every country in the contemporary world, including physical boundaries, their historical evolution, and border-related conflicts with other countries.
Nation Shapes: The Story behind the World's Borders examines the importance of country boundaries, the disconnects between these borders, related factors such as cultures, religions, and economies, and how conflicts over boundaries between neighboring countries are articulated.

The book is organized geographically and by region of the world: the Americas, Africa, Europe, the Middle East, South and Southeast Asia, East and Southeast Asia, and Australia and Oceania. It provides comprehensive descriptions of the boundaries of each country in the world, the historical evolution of these boundaries, and current and potential future boundary disputes and conflicts. While the work contains an entry for each country, the emphasis is on countries of major importance in the modern global economy.
