context_page_description: The Yongle Emperor — personal name Zhu Di — was the third Emperor of the Ming dynasty, reigning from 1402 to 1424.
  Zhu Di was the fourth son of the Hongwu Emperor, the founder of the Ming dynasty. He was originally enfeoffed as the Prince of Yan in May 1370, with the capital of his princedom at Beiping. Amid the continuing struggle against the Mongols of the Northern Yuan dynasty, Zhu Di consolidated his own power and eliminated rivals such as the general Lan Yu. He initially accepted his father's appointment of his eldest brother Zhu Biao and then his nephew Zhu Yunwen as crown prince, but when Zhu Yunwen ascended the throne as the Jianwen Emperor and began executing and demoting his powerful uncles, Zhu Di found pretext for rising in rebellion against his nephew. Assisted in large part by eunuchs mistreated by the Hongwu and Jianwen Emperors, who both favored the Confucian scholar-bureaucrats, Zhu Di survived the initial attacks on his princedom and drove south to launch the Jingnan Campaign against the Jianwen Emperor in Nanjing.
context_section_description: After the Yongle Emperor's overthrow of the Jianwen Emperor, China's countryside was devastated. The fragile new economy had to deal with low production and depopulation. The Yongle Emperor laid out a long and extensive plan to strengthen and stabilise the new economy, but first he had to silence dissension. He created an elaborate system of censors to remove corrupt officials from office that spread such rumors. The emperor dispatched some of his most trusted officers to reveal or destroy secret societies, bandits, and loyalists to his other relatives. To strengthen the economy, he fought population decline, using the most he could from the existing labour force, and maximising textile and agricultural production.
  The Yongle Emperor also worked to reclaim production rich regions such as the Lower Yangtze Delta and called for a massive reconstruction of the Grand Canal. During his reign, the Grand Canal was almost completely rebuilt and was eventually moving imported goods from all over the world. The Yongle Emperor's short-term goal was to revitalise northern urban centres, especially his new capital at Beijing. Before the Grand Canal was rebuilt, grain was transferred to Beijing in two ways; one route was simply via the East China Sea, from the port of Liujiagang (near Suzhou); the other was a far more laborious process of transferring the grain from large to small shallow barges (after passing the Huai River and having to cross southwestern Shandong), then transferred back to large river barges on the Yellow River before finally reaching Beijing. With the necessary tribute grain shipments of four million shi (one shi equal to 107 liters) to the north each year, both processes became incredibly inefficient. It was a magistrate of Jining, Shandong who sent a memorandum to the Yongle Emperor protesting the current method of grain shipment, a request that the emperor ultimately granted.
  The Yongle Emperor ambitiously planned to move his capital to Beijing. According to a popular legend, the capital was moved when the emperor's advisers brought the emperor to the hills surrounding Nanjing and pointed out the emperor's palace showing the vulnerability of the palace to artillery attack.
  The emperor planned to build a massive network of structures in Beijing in which government offices, officials, and the imperial family resided. After a painfully long construction time (1407–1420), the Forbidden City was finally completed and became the imperial capital for the next 500 years.
  The Yongle Emperor finalised the architectural ensemble of his father's Ming Xiaoling Mausoleum in Nanjing by erecting a monumental "Square Pavilion" (Sifangcheng) with an eight-metre-tall tortoise-borne stele, extolling the merits and virtues of the Hongwu Emperor. In fact, the Yongle Emperor's original idea for the memorial was to erect an unprecedented stele 73 metres tall. However, due to the impossibility of moving or erecting the giant parts of that monuments, they have been left unfinished in Yangshan Quarry, where they remain to this day.
  Even though the Hongwu Emperor may have meant for his descendants to be buried near his own Xiaoling Mausoleum (this was how the Hongwu Emperor's heir apparent, Zhu Biao was buried), the Yongle Emperor's relocation of the capital to Beijing necessitated the creation of a new imperial burial ground. On the advice of fengshui experts, the Yongle Emperor chose a site north of Beijing, where he and his successors were to be buried. Over the next two centuries, thirteen emperors in total were laid to rest in the Ming Tombs.
