China, famously, built the Great Wall to defend against nomadic groups from the Eurasian steppe. For two millennia, China interacted with groups from the north: The Xiongnu, the Mongols, the Manchus, and the Russians. They defended against raids, got invaded by the north, and tried to launch diplomatic relations.

John Man, in his book Conquering the North: China, Russia, Mongolia: 2,000 Years of Conflict (Oneworld Publications, 2025), takes on this long history, combining it with his own on-the-ground experience seeing some of this history for himself. He starts with the Xiongnu—a nomadic group that’s so unknown, historically, that we’re forced to use the pejorative Chinese term for them—all the way to the Second World War, and the seminal Battle of Khalkin Gol, which halted the Japanese advance into Northern Asia.

John Man is a historian specializing in Mongolia and the relationship between Mongol and Chinese cultures. He studied Mongolian as a post-graduate, and after a brief career in journalism and publishing, he turned to writing. John Man’s books have been published in over twenty languages around the world and include bestselling biographies of Chinggis Khan, Kublai Khan and Attila the Hun, as well as histories of the Great Wall of China and the Mongolian Empire.
