Renaming the dynasty

In 1635, Hong Taiji changed the name of his people from Jurchen (Manchu: jušen) to Manchu, or manju in the Manchu language. The original meaning of Manju is not known and so the reasons for its adoption remain opaque. There are many theories as to the reason for the choice of name but two of the most commonly cited are its sounding similar to the Manchu word for "brave" and a possible connection with the Bodhisattva Manjusri, the Bodhisattva of Wisdom, of whom Nurhaci claimed to be an incarnation.

The dynastic name Later Jin was a direct reference to the Jin dynasty founded by the Jurchen people, who ruled northern China from 1115 to 1234. As such, the name was likely to be viewed as closely tied to the Jurchens and would perhaps evoke hostility from ethnic Han who viewed the Song dynasty, rival state to the Jin, as the legitimate rulers of China at that time. Hong Taiji's ambition was to conquer China proper and overthrow the Ming dynasty, and to do that required not only a powerful military force but also an effective bureaucratic administration. For this, he used the obvious model, that of the Ming government, and recruited Ming officials to his cause. If the name of Later Jin would prove an impediment to his goal among the Han people, then it was not too much to change it. At the same time, Hong Taiji conquered the territory north of Shanhai pass by Ming Dynasty and Ligdan Khan in Inner Mongolia. He won one of the Yuan dynasty's imperial jade seal (Chinese: 制 誥 之 寶) and a golden Buddha called "Mahakala". In April 1636, Mongol nobility of Inner Mongolia, Manchu nobility and the Han mandarin held the Kurultai in Shenyang, recommended khan of Later Jin to be the emperor of Great Qing empire. Russian archive contains translations of the 1636 year Hong Taiji decree with the provision that after the fall of the Qing dynasty Mongols will return to their previous laws, i.e. independence. Whatever the precise motivation, Hong Taiji proclaimed the establishment of the Qing dynasty and also changed his era name to Chóngdé in 1636. The reasons for the choice of Qing as the new name are likewise unclear, although it has been speculated that the sound – Jin and Qing are pronounced similarly in Manchu – or wuxing theory – traditional ideas held that fire, associated with the character for Ming, was overcome by water, associated with the character for Qing – may have influenced the choice. Another possible reason may be that Hong Taiji changed the name of the dynasty from (Later) Jin to Qing in 1636 because of internecine fraternal struggle and skirmish between brothers and half brothers for the throne.

According to Taoist philosophy,the name Jin has the meaning of metal and fire in its constituent,thereby igniting the tempers of the brothers of the Manchu Royal household into open conflicts and wars.Hong Taiji therefore adopted the new name of Great Qing (大清), the Chinese character of which has the water symbol on its left hand side. The name, which means clear and transparent, with its water symbol was hoped to put out the feud among the brothers of the Manchu Royal household.

Hongtaiji claimed that the progenitor of his Aisin Gioro clan, Bukūri Yongšon (布庫里雍順), was conceived from a virgin birth. According to the legend, three heavenly maidens, namely Enggulen (恩古倫), Jenggulen (正古倫) and Fekulen (佛庫倫), were bathing at a lake called Bulhūri Omo near the Changbai Mountains. A magpie dropped a piece of red fruit near Fekulen, who ate it. She then became pregnant with Bukūri Yongšon. However, another older version of the story by the Hurha (Hurka) tribe member Muksike recorded in 1635 contradicts Hongtaiji's version on location, claiming that it was in Heilongjiang province close to the Amur river where Bulhuri lake was located where the "heavenly maidens" took their bath. This was recorded in the Jiu Manzhou Dang and his much shorter and simpler in addition to being older. This is believed to be the original version and Hongtaiji changed it to Changbai mountain. It shows that the Aisin Gioro clan originated in the Amur area and the Heje (Hezhen) and other Amur valley Jurchen tribes had an oral version of the same tale. It also fits with Jurchen history since some ancestors of the Manchus originated north before the 14th-15th centuries in the Amur and only later moved south.
