The Golden Age under Emperor Yongle's Reign

In 1402, the Prince of Yan became emperor of the Ming Dynasty (Chengzu), with Yongle as his era name. Emperor Yongle was determined to make great achievements and win the allegiance of neighbouring countries. As his original fief Beiping enjoyed significant geographic advantages, a more favourable site for the seat of his imperial government, he ordered in the first year of his reign that Beiping be renamed Beijing. Preparations were then set afoot for relocating the capital there.
