Portuguese diplomat
Fernão Pires de Andrade arrived at the mouth of the
Pearl River in June 1517 and asked the naval commander of
Nantou for permission to take his ships to
Guangzhou. After a month with no definitive reply, Andrade decided to sail up the river to Guangzhou without permission from Ming authorities. When they arrived the Portuguese ships discharged cannon fire as a friendly salute, however this was not seen as a friendly gesture by the local Chinese, who were greatly alarmed by the noise. The Portuguese explained that the Chinese traders did the same thing in
Malacca, but the local officials only became even more suspicious as Chinese overseas trade was forbidden under Ming law. When official reception from Guangzhou arrived, tensions relaxed, and the Portuguese were received with much pomp as well as the right to trade their goods for silk and porcelain.
Tomé Pires and seven other Portuguese as well as their slaves were given lodging for the embassy. A Portuguese record states that they had made a good impression. Andrade's negotiations with Ming officials were thwarted when his brother Simão de Andrade arrived in August 1519. Simão immediately made a bad impression upon the locals of Tunmen, who had previously been open to all foreigners. Upon arriving with three ships, Simão executed a Portuguese citizen and built a fort on Tunmen, barring other foreigners from conducting trade. When a Ming official arrived to inquire as to the situation, Simão became aggressive and knocked off his hat. Following this, Simão began purchasing as well as kidnapping child slaves along the Chinese coast to sell in
Portuguese Malacca. Even children from well-off families were stolen and found years later at Diu in western India. Rumors that Simão and other Portuguese were cannibalizing children for food spread across China. Simão's pirating activities greatly angered both the Chinese people and the court, which led Ming officials to order the eviction of the Tunmen Portuguese. The Portuguese embassy arrived in
Nanjing in May 1520, but news of Simão de Andrade's conduct had reached
Beijing, as had the ambassadors from the
exiled King of Malacca bringing complaints about the Portuguese. Ming officials sent
memorials to the throne that condemned the Portuguese conquest of Malacca and advocated for the rejection of their embassy. The
Zhengde Emperor died on 20 April 1521. The newly appointed
Grand Secretary,
Yang Tinghe, announced the rejection of the Portuguese embassy the day following the emperor's death. The Portuguese embassy left for Guangzhou, where they arrived in September. ==Battle==
