Ming Grand Canal Grain Transport

Timeline

1. c. 1368–1420Beijing · North ChinaAfter the early Ming established its capital at Nanjing, northbound demand was limited; after the Yongle relocation to Beijing, grain transport became the core mechanism supplying the capital's military and civilian grain, with canal dredging and grain-boat management brought under the Ministry of Revenue, Ministry of Works, and the Grain Transport Governor-General system.
2. 1630–1640Huai'an-Linqing canal hub · JiangsuIn the 1630s, silted channels, added labor levies, and local unrest intertwined, with frequent grain-boat delays and losses; the court repeatedly debated combining sea and canal transport, but fiscal and military crises placed unprecedented pressure on the grain transport system.
3. c. 1640–1644Tongzhou grain transport wharf · BeijingAs Li Zicheng and outside forces advanced, grain transport routes were repeatedly cut, and the final transfer link from Tongzhou to Beijing failed; Ming grain transport was interrupted amid the regime change, leaving an institutional legacy for Qing grain transport reform.
