The successful reconstruction of the Grand Canal linking northern China with the rich rice fields of the Yangzi in 1411 was a crucial moment, signalling a greatly reduced need for coastal shipping and, therefore, also for a navy. For almost four and a half centuries, from the consolidation of the Song Empire until the remarkable seafaring expeditions of the early Ming (1405-33), China was the greatest maritime nation in the world – using big compartmented ships (with up to four decks, four or five masts, and a dozen sails), steered by a sternpost rudder, guided by charts and compass, and able to carry 500 men. [214] The ships used by Zheng He for his great voyages to South-East Asia, the Indian Ocean and the east coast of Africa in the early fifteenth century were by far the most advanced in the world. From the moment the voyages were completed, however, China ’s maritime prowess fell into steep decline. In 1436 the construction of seagoing ships was banned and the number of smaller vessels built was reduced. The reason for this growing isolation and introspection is not entirely clear. It would appear that the failure to continue with Zheng He’s great voyages was the result of several factors: a political shift in the attitude of the Ming dynasty; the moving of the imperial capital from Nanjing to Beijing in 1421, which led to heightened sensitivities about the northern border and reduced interest in oceanic and coastal priorities; and growing concern about both the cost of the maritime voyages and the relative failure of the military expeditions against the Mongols in the north. [215] There was also an anxiety that the coastal centres, with their links to other lands, might act as an alternative source of power, the maintenance of social order and control always being a prime consideration for Chinese rulers. Perhaps also the underlying Chinese belief that their civilization was far superior to those of the barbarians (especially the nomadic cultures to its north, [216] which intensified under the Ming in an ethnic reaction to the previous Mongol rule, made such an autarchic and isolationist view seem natural.
Between 1500 and 1800, stagnation gave way to vigorous economic growth and reasonable prosperity. There was a steady increase in the food supply, due to an increase in land under cultivation – the result of migration and settlement in the western and central provinces, greater productivity (including the use of new crops like corn and peanuts) and better irrigation. [217] These developments sustained a fivefold increase in China ’s population between 1400 and 1800, whereas between 1300 and 1400 it had fallen sharply. [218] China ’s performance during this period has tended to be overshadowed by the dynamism of the earlier medieval economic revolution; unlike during the Song dynasty, this later growth was achieved with relatively little new invention. In the eighteenth century China remained the world’s largest economy, followed by India, with Europe as a secondary player. Adam Smith, who saw China as an exemplar of market-based development, observed in 1776 that ‘ China is a much richer country than any part of Europe.’ [219] It was not until 1850, indeed, that London was to displace Beijing as the world’s largest city.
