Southern Song, 1127–1279 CE

Autocracy · Monarchy · East Asia · Mongol Century era

A commercially and technologically advanced Chinese state on the Yangtze and south, holding against the Jin and then the Mongols behind a strong bureaucracy.

After losing the north to the Jin, the Song court re-established itself at Hangzhou and governed a densely commercialized, monetized south through an examination-recruited scholar-bureaucracy. The period saw advances in printing, gunpowder weapons, shipping and Neo-Confucian thought alongside sustained military pressure from the steppe. Decades of war with the Jin gave way to the Mongol campaigns that ended the dynasty in 1279.
