A divided but wealthy empire
The Song dynasty ruled China from 960 to 1279. It is split into two phases. The Northern Song (960 to 1127) had its capital at Kaifeng, on the Yellow River plain. In 1127 the Jurchen, a people from the northeast who had founded the Jin state, captured Kaifeng and took the emperor prisoner. A member of the Song family escaped south and re-established the dynasty at Hangzhou, beginning the Southern Song (1127 to 1279). The Song never controlled the far north or the northwest, and paid large sums to neighboring states for peace. Yet its economy was among the most productive in the world at the time.
Farming and population
Much of the wealth came from the land. Farmers in the south adopted faster-ripening varieties of rice, often connected to rice brought from Champa in Southeast Asia, which allowed two crops a year in some places. Irrigation, new tools and improved roads and canals moved grain to growing cities. Estimates suggest that China’s population grew substantially in this period, perhaps reaching 100 million or more by around 1100, though such figures are rough.
Cities and daily life
Song cities were remarkable for their size and variety. Kaifeng and later Hangzhou are often said to have had populations approaching or exceeding a million, though counts are uncertain and depend on how the surrounding districts were included. By comparison, even the largest cities in western Europe were far smaller. Medieval towns such as Paris or Florence held tens of thousands.
Earlier Chinese cities were laid out with walled wards and strict curfews. In the Song, these controls loosened. Shops opened onto streets, night markets operated, and entertainment districts offered storytelling, puppet shows, theater and teahouses. Writers described restaurants with menus, specialist food stalls and rental services for banquets. Fire was a constant danger in crowded wooden cities, so Hangzhou kept watchtowers and organized fire-fighting units.
The famous scroll painting often called “Along the River During the Qingming Festival” is traditionally linked to Kaifeng and shows a busy riverside city, though scholars debate what exactly it depicts.
Marco Polo later described Hangzhou in glowing terms, calling it among the finest cities in the world, although the reliability of his travel account has been debated.
Printing
Printing from carved wooden blocks was already used in China before the Song, notably for Buddhist texts. In the Song, block printing grew into a large industry that produced classics, histories, medical works, farming manuals and government documents. Movable type is credited to an artisan named Bi Sheng, who worked with baked clay type in the 1040s. Because Chinese uses thousands of characters, carving whole pages in blocks often remained more practical than setting individual pieces of type, so movable type did not replace block printing at once.
This matters for comparison with later events in Europe. The printing press, with metal type, appeared in Europe in the 15th century. It developed in a different context, and whether any knowledge from East Asia influenced it is not clearly established.
Paper money
Heavy copper coins were a burden in large transactions. In Sichuan, merchants began using paper notes, called jiaozi, as a form of receipt for deposited coins. The government took over issuing them in the early 11th century. Later notes, like the huizi, circulated more widely. Overissue could cause inflation, especially when governments printed notes to cover military costs, and the Song experience is often cited as an early lesson in this problem. Paper money mattered because it supported credit and money transfers over long distances.
Technology
The Song period saw many practical inventions and improvements.
- Compass. Magnetized needles were used for navigation at sea by the Song period, helping long-distance shipping.
- Gunpowder. Earlier discovered, it was now used for weapons, such as fire arrows, bombs and early tubes that fired projectiles.
- Astronomy and clocks. Su Song led the construction of a large water-driven astronomical clock tower in Kaifeng around 1090.
- Iron and coal. Iron output rose markedly, with coal being used as fuel in some regions.
- Shipbuilding. Larger ships with watertight compartments and rudders supported overseas trade.
Government and learning
Officials were chosen largely through civil service examinations based on the Confucian classics, which gave educated families a path to power, although wealth and connections still mattered. Neo-Confucian thought, which shaped later Chinese ideas for centuries, took form in these years.
The end of the Song
The Mongols, led after Genghis Khan by his descendants, conquered the Jin state and then spent decades fighting the Southern Song. Kublai Khan completed the conquest in 1279, ending the dynasty. The Song legacy of commerce, printing and technology, however, outlasted it.
