The Age of Walls: How Barriers Between Nations Are Changing Our World

Tim Marshall, the New York Times bestselling author of Prisoners of Geography , analyzes the most urgent and tenacious topics in global politics and international relations by examining the borders, walls, and boundaries that divide countries and their populations.

The globe has always been a world of walls, from the Great Wall of China to Hadrian’s Wall to the Berlin Wall. But a new age of isolationism and economic nationalism is upon us, visible not just in Trump’s obsession with building a wall on the Mexico border or in Britain’s Brexit vote but in many other places as well. China has the great Firewall, holding back Western culture. Europe’s countries are walling themselves against immigrants, terrorism, and currency issues. South Africa has heavily gated communities, and massive walls or fences separate people in the Middle East, Korea, Sudan, India, and other places around the world.

In fact, at least sixty-five countries, more than a third of the world’s nation-states, have barriers along their borders. There are many reasons why walls go up, because we are divided in many ways: wealth, race, religion, and politics, to name a few. Understanding what is behind these divisions is essential to understanding much of what’s going on in the world today.

As with Marshall’s first two books, The Age of Walls is a brisk read, divided by geographic region. He provides an engaging context that is often missing from political discussion and draws on his real life experiences as a reporter from hotspots around the globe. He examines how walls (which Marshall calls “monuments to the failure of politics”), borders, and barriers have been shaping our political landscape for hundreds of years, and especially since 2001, and how they figure in the diplomatic relations and geo-political events of today.
