Ming Salt Monopoly

Timeline

1. 1368–1424Nanjing · Nanjing CityThe Hongwu Emperor rebuilt the salt-field zaohu system and salt transport commissions on the Yuan model, establishing the state monopoly on salt production and the 'official supervision, merchant sale' framework in which merchants exchanged grain for salt certificates, laying the institutional foundation for the Ming salt monopoly.
2. 1476–1572Huai'an · Huai'an CityFrom the Chenghua era onward the gang system spread in Huai'an and elsewhere; salt merchants contracted for certificate quotas organized by 'gang,' and merchant guilds such as the Huizhou merchants accumulated capital through salt certificates, shifting the monopoly from pure administrative control to a combined administrative-commercial organization.
3. 1573–1580Yangzhou · Yangzhou CityIn the early Wanli era Zhang Juzheng and others pushed fiscal reform; salt certificate prices, supplementary certificates for surplus salt, and crackdowns on smuggled salt became priorities for the Ministry of Revenue and salt transport commissions. 1570s Huai salt administration archives show intensifying conflicts among gang merchants, certificate prices, and zaohu livelihoods, with the monopoly system under pressure for reform.
4. 1580–1644Beijing · Beijing CityAfter the 1580s the gang system ossified, certificate prices soared, and smuggling spread; repeated late Ming deliberations on salt failed to achieve fundamental reform, and the salt monopoly organization remained persistently unbalanced between fiscal needs and market vitality until the fall of the Ming.
