Ming Chengzu Zhu Di was the third emperor of the Ming Dynasty and the most accomplished emperor after his father, who snatched the throne from his nephew Zhu Yunjiao through the "Battle of Jingnan". In the third year of Jianwen (1402), Zhu Di took the throne in Nanjing, changing the name "Yongle".
At the beginning of the Yongle year, in order to consolidate the imperial throne and restore the titles of various feudal lords during the Jianwen Emperor period, Zhu Di began to set up a cabinet to fill the vacancies in the administrative organs after the abolition of Zhongshu Province. Favoring eunuchs, restoring the Jinyi guards that were abolished during the Hongwu period, setting up the town guard internal ministers and the East Factory Yamen, the factory guards combined forces, and developed and strengthened the autocratic rule. Zhu Di arose in Beiping, so he attached great importance to the management of the north, and in the seventh year of Yongle (1409), he began to build the Changling Tomb of Tianshou Mountain in Beijing, basing himself in the north, and at the same time, striving to establish friendly relations with the Mongols. The Tatar and Valar ministries successively accepted the titles of the Ming government. In the fourth year of Yongle (1406), the construction of the Forbidden City in Beijing began, the eighteenth year of Yongle (1420) was completed, and in the nineteenth year of Yongle (1421), the Ming Dynasty officially moved the capital to Beijing.
After the Battle of Jingnan, the weeds along the Huaibei Plain were blocked, production was seriously damaged, and a large number of peasants were displaced. Zhu Di set out to restore people's livelihood and ordered the disaster-stricken people in the prefectures and counties of the North China Plain to be exempted from the three-year differential tax. For the people who are ready to emigrate, they are ordered to return to their natural origins and resume their jobs, and the seeds and cattle tools they need are paid by the government. Zhu Di repeatedly advised the people to return to their fields and do everything possible to appease the displaced people to resume their business. In November of the first year of Yongle (1403), Ming Chengzu told his ministers that the common people had no choice but to leave their hometowns, and if they had resumed their business, the magistrates should pay a generous pension. Reclaim the land and stop collecting taxes." Zhu Di's approach was affirmed by the common people, and a large number of displaced people quickly returned to the fields, so that the broken agricultural production was quickly restored. Due to the impact of successive years of war, the land in many places is deserted and no one cultivates it. In order to combine farmers and land and develop a large amount of wasteland, Zhu Di also carried out large-scale migration across the country. Zhu Di was extremely strict with all local officials, requiring all local officials to have a deep understanding of the people's feelings and reflect the people's sufferings to the imperial court at any time. Ordered local officials or people's opinion observers sent by the central authorities to arrest and punish those who see the sufferings of the people and do not report them truthfully. In the imperial court, the civil official system was improved, and the prototype of the later cabinet system was gradually formed in the imperial court. In the third year of Yongle (1405), Zheng He served as the envoy of the mission and began a long voyage at sea, which was Zheng He's voyage to the West during the Yongle years. In the first year of Yongle (1403), he began to compile the Yongle Canon, which was finalized in the fifth year of Yongle (1407), and Zhu Di personally wrote the preface and gave it the name "Yongle Canon". It laid the ideological and organizational foundation for the development of politics, economy, military, culture and other aspects at that time, and was called "Yongle Prosperous Era" in history.
From the fourth year of Yongle (1406) to the twenty-second year of Yongle (1424), Zhu Di marched south to the north, from Walla and Tatar to the north, and to Shandong and Henan in the south. On July 18, 1424, the twenty-second year of Yongle, Zhu Di died on the way back to the division during the Northern Expedition.
