Quanzhou was blooming into a seaport under the reign of the Min Kingdom, and is the largest seaport in the world. Its population is also greater than Fuzhou. Due to the Ispah Rebellion, Quanzhou was severely damaged. In the early Ming dynasty, Quanzhou was the staging area and supply depot of Zheng He's naval expeditions. Further development was severely hampered by the sea trade ban of the Ming dynasty, and the area was superseded by nearby ports of Guangzhou, Hangzhou, Ningbo and Shanghai despite the lifting of the ban in 1550. Large scale piracy by Wokou (Japanese pirates) was eventually wiped out by Chinese military and Japanese authority of Toyotomi Hideyoshi.
