14 years (604-6 18 years) During Yang Guang's reign, he was both civil and military and made outstanding achievements. He unified the whole country, built canals, built the eastern capital, toured Zhangye in the west, reformed and innovated, toured Jiangdu three times and Liaodong three times.
The achievements of Emperor Yang Di:
First, personally command and complete the reunification of the motherland (unify the whole country)
In 589 AD, Yang Guang, who was only 20 years old, was worshipped as the Grand Marshal of Sui Dynasty, and led 565,438+10,000 troops to attack the prosperous Chen Dynasty, thus completing reunification.
Second, building a smooth national lifeline (building a canal) and (building an eastern capital)
In 605 AD, it took six years to dig Tongji Canal, Han Canal and Yongji Canal. The Grand Canal connects Qiantang River, Yangtze River, Huaihe River, Yellow River and Haihe River, from Zhuo Jun in the north to Yuhang in the south. It winds more than 5000 miles from north to south. Many granaries have been built along the canal as places for transshipment or storage.
It was also in the first year of Daye (AD 605) that Yang Di sent Su Yang and others to build Luoyang City. At that time, the capital Chang 'an was in the northwest, and the road to the east was not smooth, which affected the smooth implementation of state laws and regulations. Luoyang is located in the center of the country, which can effectively govern the south of the Yangtze River, control the north and consolidate the country.
Thirdly, personally exploring the territory and opening the Silk Road (visiting Zhangye in the west) further contributed to the northwest Gansu, Qinghai and Xinjiang becoming an inseparable part of China.
Fourth, attach importance to education, seek classics, build imperial examinations, and amend the law (reform and innovation)
Yang Guang resumed the study of imperial academy, imperial academy and County abolished by Emperor Wendi of Sui Dynasty. He also compiled 400 copies of Changzhou Jade Mirror and 1200 copies of District Records, which contributed to the preservation of ancient books in China.
Yang Guang set up a school, visited the scattered books and protected them.
Yang Guang established the imperial examination system, which had a far-reaching influence on later generations. His emphasis on knowledge rather than family status weakened the hereditary privilege of large families. This "meritocracy" reform provided an excellent opportunity for the lower class to select outstanding intellectuals, which had a far-reaching impact on later generations of China.
Yang Guang's practice of law was mainly to reform the harsh law in the last years of Emperor Wen of Sui Dynasty.
Yang Di's poetry occupies a certain position in the history of China literature and poetry.
Neglect:
Yang Di's failure is that he used the people too much, was eager for quick success and instant benefit, and wanted to make great achievements too much. Three driving Liaodong not only consumed a lot of its main army, but also brought a heavy burden to the people. The main reason is the heavy military service. The construction of the grand canal itself hurts the people and the country. A series of wars to expand the territory also consumed a lot of manpower and material resources. Emperor Yang Di was overconfident and underestimated the enemy, which led to the first time.
Unfortunately, Yang Di died in a palace coup, not at the hands of peasant rebels, but in the restoration of Xianbei people. In 6 18, Yang Di died at the hands of the Yuwen family, and his father, Emperor Wendi, won the throne from the Yuwen family of Xianbei royal family, and Xianbei nobles took advantage of the chaos to recapture it from Yang Guang. After Yang Di was killed, under the banner of revenge for Yang Guang, he wiped out the restored Yuwen Xianbei nobles, put down the peasant uprising, defeated various governors, and finally established the Tang Dynasty. It can be said that Sui laid a solid foundation for the development and prosperity of the Tang Dynasty. Yang Di made a wedding dress for Emperor Taizong. Now Emperor Taizong has become a famous monarch, while Yang Di has become an evil and fatuous monarch. Why? Because Tang Shi is a history written by people in the Tang Dynasty, so is the history of the Sui Dynasty.
