Turchin argues that the key to the formation of an empire is a society’s capacity for collective action. He demonstrates that high levels of cooperation are found where people have to band together to fight off a common enemy, and that this kind of cooperation led to the formation of the Roman and Russian empires, and the United States. But as empires grow, the rich get richer and the poor get poorer, conflict replaces cooperation, and dissolution inevitably follows. Eloquently argued and rich with historical examples, War and Peace and War offers a bold new theory about the course of world history with implications for nations today.","forthcoming":false,"isbn13":"9780452288195","publication_date":"20070227","publisher":"Penguin Publishing Group","slug":"war-and-peace-and-war","subtitle":"The Rise and Fall of Empires","title":"War and Peace and War"},"discovery":{"categories":{"all":[{"bisac_code":"HIS027130","confidence_band":"medium","label":"Other Military Conflicts","score":0.772,"source":"bisac_hint_model"},{"bisac_code":"HIS027060","confidence_band":"medium","label":"Military Strategy","score":0.7667,"source":"bisac_hint_model"},{"bisac_code":"POL011010","confidence_band":"medium","label":"Diplomacy","score":0.7637,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"HIS027130","confidence_band":"medium","label":"Other Military Conflicts","score":0.772,"source":"bisac_hint_model"},{"bisac_code":"HIS027060","confidence_band":"medium","label":"Military Strategy","score":0.7667,"source":"bisac_hint_model"},{"bisac_code":"POL011010","confidence_band":"medium","label":"Diplomacy","score":0.7637,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"HIS027220","confidence_band":"high","label":"Ancient Warfare","score":1,"source":"onix_publisher_code"},{"bisac_code":"HIS037000","confidence_band":"high","label":"World History","score":1,"source":"onix_publisher_code"},{"bisac_code":"SOC002010","confidence_band":"high","label":"How Cultures Work","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Other Military Conflicts","score":0.772,"slug":"other-military-conflicts"},{"label":"Military Strategy","score":0.7667,"slug":"military-strategy"},{"label":"Diplomacy","score":0.7637,"slug":"diplomacy"}],"reader_fit":["Good for readers who enjoy Other Military Conflicts","Good for readers interested in gifts","Good for fans of History"],"related_lists":[],"series":null,"similar_books":[{"authors":["David Petraeus","Andrew Roberts","Robert Fass","Harper"],"book_id":"9780063293144","cover_image_url":"https://img.bookfrontier.com/9780063293144.jpg?v=20260417T232332Z%3A2026-04-17T23%3A23%3A32Z","score":20.413,"title":"Conflict","url":"https://bookfrontier.com/books/9780063293144"},{"authors":["Paul Thomas Chamberlin"],"book_id":"9780062367204","cover_image_url":"https://img.bookfrontier.com/9780062367204.jpg?v=20260417T232332Z%3A2026-04-17T23%3A23%3A32Z","score":17.8564,"title":"The Cold War's Killing Fields","url":"https://bookfrontier.com/books/9780062367204"},{"authors":["David Bryson","Brett Boles","Robert Spalding","Penguin Audio"],"book_id":"9780593331040","cover_image_url":"https://img.bookfrontier.com/9780593331040.jpg?v=20260417T232332Z%3A2026-04-17T23%3A23%3A32Z","score":17.4889,"title":"War Without Rules","url":"https://bookfrontier.com/books/9780593331040"},{"authors":["Michael J.
