The Ming dynasty of the 17th century had relaxed its age old practice of banning maritime trade, allowing the Chinese coast to bustle with commercial activity. The Ming navy, however, had been poorly maintained and ineffectual, such that pirates had practically controlled this trade. The pirate leader Zheng Zhilong in particular dominated the Fujian coast, his ships decked with European cannons and mercenaries from Japan to Africa. The Ming court, in its decline, recruited Zheng Zhilong in 1628 rather than to try and destroy him. Although the more piratical elements of his fleet deserted him after he surrendered to the Ming, Zheng's new status as a Ming admiral allowed him to go after his former lieutenants. He was aided in this anti-pirate campaign by the Dutch under the governor of Formosa (Taiwan), Hans Putmans.
