The Reign of the Jiajing Emperor
Jiajing was capable and hard-working in his early years, and even when he withdrew from court he continued to read memorials and to decide matters through his grand secretaries. He was also suspicious, vindictive and quick to punish, and officials who displeased him were often beaten, imprisoned or executed.
From about 1539 he stopped holding regular court audiences, and after 1542 he lived mostly in the West Park, the palace gardens beside the Forbidden City, surrounded by Daoist priests and a small circle of favoured officials and eunuchs.
Yan Song
The chief beneficiary was the grand secretary Yan Song, who dominated the government for some twenty years from the 1540s, together with his son Yan Shifan. Their rule became a byword for corruption. The official Yang Jisheng, who denounced Yan Song in 1553, was imprisoned and later executed. Yan Song finally fell from favour in 1562, and Yan Shifan was executed in 1565.
In 1566 the official Hai Rui submitted a famous memorial criticising the emperor himself for neglecting government in favour of Daoist pursuits. He was thrown into prison, but was released after Jiajing's death and became a celebrated model of the upright official.
Mongols and Pirates
The northern frontier was under constant pressure from the Mongol leader Altan Khan, who demanded the right to trade. In 1550 his horsemen reached the outskirts of Beijing and plundered the surrounding countryside. A horse market was opened briefly in 1551, but a lasting settlement was reached only in 1571, under Jiajing's son.
At the same time the south-east coast suffered raids by the wokou, pirates who were Japanese in name but largely Chinese in fact, closely tied to the smuggling trade that the Ming ban on private overseas commerce encouraged. The raids were at their worst in the 1550s and were brought under control by commanders such as Qi Jiguang and Yu Dayou.
In 1553 an outer wall was built to enclose the southern suburbs of Beijing. In 1556 Shaanxi was struck by the deadliest earthquake in recorded history, in which several hundred thousand people died.
