The Sui and Tang Dynasties are the collective name of the two dynasties, Sui Dynasty and Tang Dynasty.
Sui and Tang Dynasties (581-907); Sui Dynasty (581-618); Tang Dynasty (618-907).
The Sui Dynasty (581-619) was a unified dynasty after more than 200 years of division between the Northern and Southern Dynasties. It was an important dynasty that inherited the Southern and Northern Dynasties and started the Tang Dynasty. Historians often call it the Sui and Tang Dynasties together with the Tang Dynasty. The Tang Dynasty lasted for 22 dynasties and lasted for 289 years. It was one of the dynasties with the longest unification time and the most powerful national power in Chinese history.

The Northern Zhou Dynasty destroyed the Northern Qi Dynasty in 577 and unified North China and the country prospered. However, Emperor Xuan Yun of the Northern Zhou Dynasty was extravagant and glitzy, indulged in wine and sex, was politically corrupt, and had five queens at the same time. Yang Jian, a foreign relative, took the opportunity to send important ministers of the Northern Zhou Dynasty abroad, and the government gradually came under his control. Emperor Xuan of the Northern Zhou Dynasty died of illness on June 8, 580. Yang Jian supported the young Emperor Jing of the Northern Zhou Dynasty, Yuwen Chan, and assisted the government as the prime minister.
On March 4, 581, Emperor Jing of the Northern Zhou Dynasty abdicated to Yang Jian, and Yang Jian ascended the throne as Emperor Wen of the Sui Dynasty. The Sui Dynasty was founded and the Northern Zhou Dynasty fell. Emperor Wen of the Sui Dynasty intended to destroy the Chen Dynasty in the south and adopted Gao Jiong's strategy: interfering with Chen's agricultural production in the Southern Dynasty, destroying the Chen State's military reserves, causing Chen State heavy losses and exhaustion.
After Emperor Wen of the Sui Dynasty won the war between the Sui Dynasty and the Turks, he deposed Xiao Cong, the rear lord of the Western Liang Dynasty, on October 26, 587, and the Western Liang Dynasty died. The following year, the Sui Dynasty launched the battle to destroy Chen. Emperor Wen of the Sui Dynasty appointed Yang Guang, Yang Jun and Yang Su as marching marshals. However, the actual command was Gao Jiong. The three armies consulted and all took the lead at Jiong, and divided the troops into eight groups to attack Chen.
On February 10, 589, the coalition forces entered Jiankang City and captured Empress Chen. Soon, the Chen armies in various places either surrendered under the orders of Empress Chen or resisted the Sui armies and were wiped out. Only the Lingnan area was defended by Mrs. Xian. In September 590, the Sui Dynasty sent envoys Wei Yu and others to appease Lingnan. Mrs. Xian led a crowd to welcome the Sui envoys, and all the states in Lingnan became the territory of the Sui Dynasty.
At this point, the Sui Dynasty ended the division between the north and the south for more than 280 years since the Yongjia Rebellion in the Western Jin Dynasty and completed the unification of China.
In 617, Li Yuan killed Wang Wei and Gao Junya and launched a rebellion in Taiyuan. Soon, Li Yuan led his generals to break through Qu Tutong who was guarding Guanzhong and occupied Daxing City, the capital of Sui Dynasty. Li Yuan supported Yang You as emperor, who was Emperor Gong of the Sui Dynasty. He respected Emperor Yang of the Sui Dynasty as the supreme emperor, appointed himself the prime minister, and became the king of the Tang Dynasty.
As for Emperor Sui Yang in Yangzhou, he was enjoying himself and was unwilling to return to Guanzhong. Finally, he was killed by Yu Wenhuaji and other rebels in the Jiangdu coup in 618. Li Yuan took this opportunity to force Emperor Gong of the Sui Dynasty to abdicate in May of the same year and establish the Tang Dynasty, that is, Emperor Gaozu of the Tang Dynasty. The capital Daxing was renamed Chang'an.
Before entering Guanzhong, he first sent envoys to praise Li Mi of the Wagang Army who occupied Henan, making it a barrier to the east. After entering Guanzhong, he sent Li Shimin to pacify Xue Ju and Xue Rengao in Jincheng in the northwest, and sent Tang envoys An Xinggui and An Xiuren to capture Wuwei's Li Gui alive. In 620, he sent Li Shimin to defeat Liu Wuzhou and Song Jingang who invaded Hedong (now Shanxi Province).
Then Emperor Zheng of Luoyang, Shichong, and Emperor Xia of Hebei, Dou Jiande, announced an alliance to jointly fight against the Tang Dynasty. In 622, Li Shimin defeated the coalition forces, captured Dou Jiande, and Wang Shichong surrendered. Dou Jiande's remnant Liu Heitai was also defeated by Li Jiancheng, and Hebei was pacified. In 623, Fu Gong'er led the remaining troops of Du Fuwei to rebel against the Tang Dynasty in Danyang. The following year, they were captured and killed by the Tang army, and Jiangnan was pacified.
In the Lianghu area, Tang general Li Jing won the battle against Xiao Xian in Tang Dynasty in 621, and Liang Emperor Xiao Xian surrendered to Tang Dynasty in Jiangling. The following year, Feng An of Lingnan surrendered, Lin Shihong of Qianzhou died, and the entire territory of China was owned by the Tang Dynasty.
