The Qianlong Emperor (Wade-Giles: Chien-lung Emperor; born Hongli (Wade-Giles: Hung-li; Chinese: 弘曆; Manchu language: ᡥᡠᠩ ᠯᡳ; Möllendorff transliteration: hung li); 25 September 1711 – 7 February 1799) was the sixth emperor of the Manchu-led Qing Dynasty, and the fourth Qing emperor to rule over China proper. The fourth son of the Yongzheng Emperor, he reigned officially from 11 October 1735 to 8 February 1796.1 On 8 February, he abdicated in favor of his son, the Jiaqing Emperor – a filial act in order not to reign longer than his grandfather, the illustrious Kangxi Emperor. Despite his retirement, however, he retained ultimate power until his death in 1799. Although his early years saw the continuation of an era of prosperity in China, his final years saw troubles at home and abroad converge on the Qing Empire.

Even before Hongli's succession was read out to the assembled court, it was widely known who the new emperor would be. The young Hongli had been a favorite of his grandfather, Kangxi, and his father alike; Yongzheng had entrusted a number of important ritual tasks to him while Hongli was still a prince, and included him in important court discussions of military strategy. Hoping to avoid repetition of the succession crisis that had tainted his own accession to the throne, he had the name of his successor placed in a sealed box secured behind the tablet over the throne in the Palace of Heavenly Purity (Qianqing Gong 乾清宮). The name in the box was to be revealed to other members of the imperial family in the presence of all senior ministers only upon the death of the Emperor. Yongzheng died suddenly in 1735, the will was taken out and read out before the entire Qing Court, and Hongli became the 6th Manchu Emperor of China. He took the era name of Qianlong (乾隆), 乾 means heaven, 隆 means eminence, which means "Lasting Eminence".
