The construction of the Forbidden City in Beijing began in 1406 BC, was built by Judy, the founder of the Ming Dynasty, and was completed in the 18th year of Yongle in the Ming Dynasty (1420). The Forbidden City in Beijing is the imperial palace of Ming and Qing Dynasties, where 24 emperors of two generations handled government affairs and life. It is the essence of Han Palace architecture and an unparalleled masterpiece of ancient architecture.

Extended data:

Beijing was originally the fief of Judy, the prince of Yan. After the war of Jingnan, in the first year of Yongle (1403), Li Zhigang, an official of the Ministry of Rites, said that Yanjing Beiping was the emperor's "land of dragon's prosperity" and should follow Ming Taizu's example and take Fengyang as its capital.

In the fourth year of Yongle (1406), Ming Taizu wrote a book to build the Forbidden City and the city wall in Beijing on the basis of the Nanjing Forbidden City. Emperor Chu first sent personnel to all parts of the country to mine precious wood and stones, and then transported them to Beijing.

In the seventh year of Yongle (1409), Ming Chengzu took Beijing as the northern expedition base, and at the same time began to build Changling in Changping near Beijing. Building the mausoleum in Beijing instead of Nanjing proves that Ming Chengzu has made up his mind to move the capital.

In the 14th year of Yongle (14 16), Ming Chengzu called his ministers to formally discuss the move to Beijing. For the ministers who raised objections, Ming Chengzu dismissed or severely punished them one by one, and no one dared to oppose moving the capital again. ?
