Why did Judy, the founder of the Ming Dynasty, build the Forbidden City? When did he start building?

In order to prepare for moving the capital to Beijing, the Ming Emperor Judy ordered the construction of the Forbidden City, and the construction of the Forbidden City officially began in 14 17. During the vassal period, Judy lived in Peiping from 1380 to 1402. Among them, in 1399, Judy launched a mutiny in the name of "Jingnan", during which she experienced a four-year war with the imperial court and finally defeated the imperial court in 1402. This year, Judy won the victory and proclaimed herself emperor in Nanjing for the sake of becoming the ancestor of the Ming Dynasty.

After Judy succeeded to the throne, his fief Beiping followed suit. 1403, Judy promoted Beiping, the land of Longxing, to Beijing at the suggestion of the courtiers such as Shangshu. At the same time, he also ordered wealthy businessmen from the south of the Yangtze River and businessmen from Shanxi to immigrate to Beijing to enrich the population of Beijing. 1406, Judy continued to order the construction of a new palace in Beijing. Judy attaches great importance to this palace. Before the formal construction, he first ordered a wide collection of all kinds of precious stones and wood from all over the world. In order to build this palace, it took eleven years to prepare the preliminary materials alone.

During this preparation period, Judy personally led many expeditions to the north, all of which were stationed in Beijing. In addition, Judy also ordered the construction of her own mausoleum, Changling, in Changping District, near Beijing. Whether building a palace or a mausoleum in Beijing, these things show Judy's intention to move to the capital. At 14 16, Judy finally made the decision to move the capital to court when the preparations for the Beijing Palace were about to be completed.

The following year, Beijing Palace officially started construction. This palace was based on the existing Nanjing Palace at that time. In addition to the main hall, an outer wall was built. This Beijing Palace, which took four years to build, is the Forbidden City, which is now the Forbidden City.
