Huangtai · Reign 618—619
The emperor who was established in Luoyang after Emperor Yang's death relied on Wang Shichong to resist Li Mi, but was eventually deposed and killed by Wang Shichong.
Yang Dong is the second son of Yang Zhao, Crown Prince of Yuande, and is granted the title of King Yue. In 616, Emperor Yang went south to Jiangdu and ordered him to stay in Luoyang, the eastern capital. Starting in 617, Li Mi of the Wagang Army besieged Luoyang for a long time, and Wang Shichong was ordered to lead his army to rescue him. In 618, news of the death of Emperor Yang came. In May, the remaining officials Duan Da, Wang Shichong, Yuan Wendou, Lu Chu and others supported Yang Dong as the throne and changed the name of Emperor Yang to Yuan Huangtai. He recruited Li Mi and asked him to block Yuwen Huaji who was heading north. In July, King Shichong killed Yuan Wendou and Lu Chu and took over the power. In September, he defeated Li Mi. In April 619, Wang Shichong deposed Yang Dong and proclaimed himself emperor with the name of Zheng. He soon killed him at the age of sixteen.

PoliticsLuoyang ascended the throne
News of Emperor Yang's death reached Luoyang. In May, seven people including Duan Da, Wang Shichong, Yuan Wendou, and Lu Chu supported Yang Dong as the throne and adopted the era name Huangtai. They were called the "Seven Nobles" at the time and were in charge of the government.
MilitaryWang Shichong's exclusive power
Yang Dong recruited Li Mi to attack Yuwen Huaji. In July, King Shichong launched a mutiny, killing Yuan Wendou and Lu Chu who advocated recruiting, and took over the government. In September, he defeated Li Mi in Mangshan, and the Wagang army collapsed.
PoliticsDeposed and killed
In April, Wang Shichong forced Yang Dong to proclaim himself emperor and named his country Zheng. Soon someone was sent to deliver poisoned wine. Yang Dong burned incense and worshiped Buddha, praying that he would not be reborn in the emperor's home in the next life. He drank the medicine but was hanged.
He became the favor of Emperor Yang by suppressing the people, and was ordered to rescue Dongdu. In 618, he defeated Li Mi and took power. In 619, he abolished Yang Dong and became independent. In 621, he was besieged by Li Shimin and surrendered.
In 618, he accepted Yang Dong's care and defeated Yuwen Huaji at Tongshan. He was immediately defeated by Wang Shichong. After surrendering to Tang Dynasty, he rebelled and was killed.
An important minister left behind in Dongdu, one of the "Seven Nobles" who supported Yang Dong, advocated recruiting Li Mi to fight against Yuwen Huaji, and conspired to get rid of Wang Shichong, but was killed after the incident was revealed.
