Foreign Affairs
Xuande inherited a failing war in Vietnam, where the Ming had ruled since Yongle's conquest of 1407. Some of his advisers opposed withdrawal, and in 1427 a relief army was sent under Liu Sheng. It was ambushed and destroyed, and Liu Sheng was killed. The emperor then accepted the inevitable: the last Ming forces withdrew in 1427–1428, and the court came to terms with Le Loi, founder of the Le dynasty, in return for tribute.
On the northern frontier, he led a force in person against Mongol raiders in 1428 while inspecting the border defences. The Ming kept up relations with the Eastern Mongol leader Arughtai, who supplied horses, until Arughtai was defeated by the Oirats and was killed in 1434 by the Oirat leader Toghon.
Relations with Japan, broken off during Yongle's reign, were restored in the early 1430s. Relations with Korea remained close, although Koreans resented the court's demands, which included young women sent for the imperial palace.
In 1430 the emperor ordered one last great voyage by Zheng He. The fleet sailed in 1431 and returned in 1433, reaching the Persian Gulf and East Africa. No further voyages of this kind were made.
Officials and Eunuchs
In 1428 the corrupt censor-in-chief Liu Guan was removed and replaced by Gu Zuo, who dismissed more than forty officials of the censorates in Beijing and Nanjing for incompetence. Some were imprisoned, demoted or banished, but none was executed. The emperor also revised the rules on military conscription and the treatment of deserters, although the hereditary military system continued to decline.
Xuande allowed eunuchs to be formally educated within the palace, and trusted them with important tasks. The growth of eunuch influence that followed became one of the serious problems of later Ming government.
Death of the Xuande Emperor
Xuande fell ill and died early in 1435, aged thirty-five. His son Zhu Qizhen, who reigned as the Zhengtong Emperor and is better known as Emperor Yingzong, was still a small child, and government passed for some years to his grandmother, Grand Empress Dowager Zhang, and the Three Yangs.
Xuande Porcelain for Collectors
The imperial kilns at Jingdezhen reached a peak under Xuande. Blue and white of the reign is painted in imported cobalt that fires to a strong, deep blue with dark, almost black spots where the pigment concentrated, a characteristic later potters tried hard to imitate. The glaze often has a slightly undulating surface, sometimes likened to orange peel. The kilns also produced fine copper-red monochromes and underglaze red, and pieces combining underglaze blue with overglaze enamels.
Xuande is the first reign in which imperial porcelain was marked regularly. The standard mark is six characters, Da Ming Xuande nian zhi (大明宣德年製, "made in the Xuande reign of the Great Ming"), written in regular script. It is found not only on the base but also along the rim, inside the mouth or elsewhere on the body.
No Ming reign mark was copied more often. Xuande marks were added to porcelain throughout the later Ming and Qing, sometimes as homage and sometimes to deceive, so a mark must always be judged together with the body, glaze and painting. In our collection we have a blue and white bowl with a Xuande mark.
