Ming Coastal Defense Military Organization

Timeline

1. c. 1541–1545Zhejiang–Fujian coast · Southeast coastIn the early 1540s wokou and smuggler forces frequently raided Zhejiang and Fujian; the existing guard and naval station organization, weakened by military decay and fragmented command, could not effectively coordinate defense, prompting the court to reconsider coastal defense organization.
2. c. 1547–1550Guards along the southeast coast · Southeast coastOfficials such as Zhu Wan pushed strict bans on private contact, reorganized naval stations and warships, and conducted cross-regional sea patrols, establishing a dedicated superintendent-of-military-affairs system that brought guards, anti-wokou troops, and local militia under unified command, shifting coastal defense from scattered garrisons to regional joint defense.
