This event hosted by UK think tank the Henry Jackson Society discusses the forces shaping our geopolitical future.
From the dawn of the modern era to the end of the Cold War, global history was defined by rivalries between great powers. In the West, this meant the struggle for supremacy in Europe and the Americas, while in the East, it encompassed those vying for control over the successor states to Genghis Khan’s empire. Between 1989 and the year 2000, great power rivalry temporarily gave way to globalization, with liberal democracy on the march and national chauvinism seemingly in retreat. But events of the past decade have made one thing abundantly clear: the great powers are back.
In The Return of the Great Powers, renowned historian and Director of the Centre for Geopolitics, Professor Brendan Simms offers a new history of the rise, fall, and return of the Great Powers in our time. He shows that over the past ten years or so, the major global actors have already resumed making decisions based on geopolitical rather than global economic considerations. Delivering a clear-eyed reckoning with today’s most pressing geopolitical issues, from the Ukraine war to the future of American dominance, ’The Return of the Great Powers’ insists that we can only understand the future of the great powers by looking to the history that forged them.
This will be a book discussion with Professor Simms about the forces shaping our geopolitical future.
