Yamen
19 Mar 1279 — The last Song fleet, carrying the court in exile, is destroyed off this headland; the chancellor Lu Xiufu takes the eight-year-old emperor on his back and steps into the sea. For the first time in history, all of China is ruled by conquerors from the steppe.
THE MOMENT IN CONTEXT
Song China was everything the steppe was not — and for forty-five years it was the conquest the machine could not finish. Look at the blue on your map: seventy million people, the world’s richest economy (paper money, blast furnaces, a merchant marine), no horse country anywhere, and a defense grid built of exactly what cavalry cannot eat: rivers, rice paddies, and walled cities provisioned by water. The Mongols’ first fifteen years of war (from 1234, the Song having helped kill the Jin — Chapter 3’s debt) win almost nothing; Möngke’s great three-front invasion of 1258–59 kills the Great Khan himself under the cliffs of Diaoyu. The steppe method — mobility, pasture, terror — has met an ecology and a state deep enough to absorb it. Khubilai’s answer, patient as a dynasty, is to stop attacking China as a steppe conqueror and start absorbing it as a Chinese claimant: he moves his capital from Karakorum’s grass to Khanbaliq (Beijing), takes the dynastic name Yuan from the Book of Changes, restores Confucian rites, builds granaries — and builds a navy, hiring the defected Song admirals the court kept insulting.
From Chapter 10 — Khubilai and the Song of The Mongol Empire, 1206–1294 (1279).
