The Bozhou rebellion, or the Yang Yinglong rebellion, was an uprising led by Yang Yinglong, a chieftain of the Miao tribes located on the border of the Ming provinces of Huguang, Guizhou, and Sichuan in southwestern China. This rebellion took place in the 1590s and was aimed at challenging the rule of the Wanli Emperor.
The Ming authorities had been dealing with issues involving Yang Yinglong since 1587. In 1589, open conflict began and continued until 1600, with a brief pause for negotiations in 1594. Following the end of the war in Korea, the task of suppressing Yang's rebellion was given to Li Hualong, an official with military experience who arrived in Chongqing in 1599. He carefully planned a spring offensive, and the fighting in 1600 lasted for 104 days. According to Li's final report, over 22,000 rebels were killed, and Yang committed suicide. As a result, his chiefdom was incorporated into the standard Chinese administrative system.
The Yang clan, descendants of a 9th-century Tang general, held control over a mountainous region on the border of Huguang, Guizhou, and Sichuan, spanning over 300 km (200 mi) from east to west and slightly less from north to south. The heart of this region was situated in Bozhou. For many centuries, the clan maintained their dominance over the area and, despite their Chinese origins, eventually assimilated and identified with the local Miao tribes. During the reign of Kublai Khan in the second half of the 13th century, they were granted the title of Xuan wei shi, or "pacification commissioner", of Bozhou. In the Ming dynasty, the chieftains of the Yang clan continued to hold the title of pacification commissioner and were given a secondary third official rank. They were also required to provide 200 tons of wood and other supplies, including horses, every three years. However, other influential clans existed in the region alongside the Yang clan, and the Ming authorities had to intervene and resolve their conflicts from time to time.
Yang Yinglong inherited his position in 1571 after his father's death. He proved himself to be a skilled commander for the Ming during battles with other native groups and Tibetans. His timber supply also gained recognition from the Ming court. Despite some officials accusing him, he was promoted to regional military commissioner and received the third major rank (3a). He became even more ambitious and viewed the Ming troops as weak. He became involved in disputes between local Miao tribes and Chinese colonists, often attacking the former. Initially, the government in Beijing refused to intervene, citing more pressing issues, and believed that Yang Yinglong was seeking personal glory, but the Ministry of War was eventually ordered to investigate and reorganize the local administration.
In 1587, Yang's actions became more extreme when he denounced his first wife under the influence of a new favorite concubine. He then proceeded to murder her family and plunder the region. The affected family reported this to the provincial authorities.
In 1590, open fighting broke out between Yang's Miao clans and their rival clans, drawing the attention of the Ming authorities. Grand Coordinator of Guizhou Ye Mengxiong () accused Yang of 24 crimes, but the regional inspector in Sichuan, Li Hualong (), proposed pardoning Yang based on his past merits. The matter became stuck in interdepartmental consultations in Beijing. Despite this, armed clashes in the region continued and Ye Mengxiong eventually requested a military campaign against Bozhou. In response, Yang surrendered to the Sichuan authorities in early 1593, hoping for a more lenient approach than in Guizhou, but to his surprise, he was sentenced to death in Chongqing. In an attempt to save himself, Yang offered to pay 20,000 liang (746 kg) of silver, raise 5,000 soldiers, and personally lead them into war in Korea. The Wanli Emperor agreed, and the military commanders in Korea eagerly awaited the arrival of Miao reinforcements. The Japanese forces withdrew before Yang arrived and he returned home.
After returning to Guizhou, Yang broke his promise,going on to ravage several prefectures and counties while disregarding his obligations to the Ming authorities. This caused alarm among local Ming officials, who wrote reports to Beijing. In the spring of 1594, Grand Coordinator Wang Jiguang (), responsible for the security of Sichuan, led an army to march against Yang. He attacked from three directions. When the Ming troops reached the Lushan Pass, Yang sent negotiators to offer submission, but his army launched a surprise attack on the unprepared Ming columns, causing heavy casualties and resulting in the loss of almost all of their supplies. The Emperor then dismissed Wang Jiguang from his position, and appointed Tan Xisi () as the grand coordinator of Sichuan and Xing Jie () as the supreme commander (zongdu) in Guizhou. A new campaign against Bozhou was planned, but was postponed due to the illness of Liu Chengsi (), the regional commander of the Sichuan troops.
In early 1595, Xing Jie arrived in Sichuan and urged Yang to surrender in order to save his life. The local powerful families also supported the war against Yang, hoping to destroy him. In the summer of 1595, Prefect of Chongqing Wang Shiqi () began a trial against Yang. He initially sent his brother to the Ming authorities, and after a month he himself appeared. Yang was tried with 12 aides, who were sentenced to death and executed. Yang was able to secure his release by paying 40,000 liang of silver and agreed to relinquish his position in favor of his sons, Yang Chaodong () and Yang Kedong (). Yang Kedong would come to Chongqing as a hostage. The Emperor considered the matter resolved and rewarded the commanders involved. Wang Shiqi was promoted to grand coordinator of eastern Sichuan.
After being released and returning home, Yang Yinglong resumed his violent ways. During this time, Yang Kedong died in Chongqing. Despite promising to pay a ransom, Yang Yinglong refused to do so. Within a year, he began leading raids into Huguang, Sichuan, and Guizhou. He even went as far as declaring himself emperor in Bozhou. Although his Miao warriors were brave and familiar with the terrain, they lacked proper equipment and were no match for a disciplined and organized army. In the beginning, they were successful in using guerrilla tactics and were able to capture supplies and weapons from defeated Ming troops, as well as loot forts and warehouses. This continued for three years, with his 100,000 Miao warriors spreading fear throughout the surrounding area. The Ming troops, however, remained resilient and continued to resist.
The Wanli Emperor, who was preoccupied with the war in Korea, postponed resolving the issues in the relatively peripheral southwest region of the empire. In an attempt to pacify the area, he sent Ma Qianxi, who had family ties to Yang, as a commissioner. Meanwhile, Wang Shiqi was transferred to Korea in 1598. Taking advantage of the situation, Yang attacked government outposts in Sichuan and Huguang, destroying them along with the villages of his local enemies. Tan Xisi requested reinforcements to suppress the rebels and was granted 2,000 men, whom he stationed at strategic points.
In 1599, following the end of the war in Korea, the Wanli Emperor turned his attention towards the affairs of the southwest region of the empire in a more organized manner. During this time, Grand Coordinator of Guizhou Jiang Dongzhi () gathered 3,000 men to combat the rebels in the spring of 1599, but they were ultimately defeated in southeastern Sichuan. As a result, the Emperor replaced Jiang Dongzhi with the experienced official Guo Zichang (). Li Hualong,
