Hong Taiji.

About Hong Taiji

Hong Taiji, sometimes rendered as Huang Taiji and occasionally referred to as Abahai in Western literature, also known by his temple name Emperor Taizong of Qing, was the second khan of the Later Jin dynasty and the founding emperor of the Qing dynasty. He was responsible for consolidating the empire that his father Nurhaci had founded and laid the groundwork for the conquest of the Ming dynasty, although he died before this was accomplished. He conquered Inner Mongolia and the remainder of Manchuria and invaded Korea, which became a Qing tributary state. He was also responsible for changing the name of the Jurchens to "Manchu" in 1635, and changing the name of his dynasty from "Great Jin" to "Great Qing" in 1636.
