Zheng Yi Sao, a Cantonese prostitute, married a pirate captain in 1801 and helped him build up his sea empire, so that by 1805 it consisted of four hundred junk ships operated by forty to sixty thousand pirates. In 1810 the Chinese government, rather than continue to suffer losses, offered the pirates amnesty if they were to retire. Zheng Yi Sao accepted and, according to one historian, led the remainder of her life peacefully, “so far as is consistent with the keeping of an infamous gambling house.”
