What is "nurhaci"

Nurhaci (; ; alternatively Nurhachi; 21 February 1559 – 30 September 1626) was a Jurchen chieftain who rose to prominence in the late 16th century in Manchuria. Nurhaci was part of the Aisin Gioro clan, and reigned from 1616 to his death in September 1626.

Nurhaci reorganised and united various Jurchen tribes (the later " Manchu"), consolidated the Eight Banners military system, and eventually launched attacks on Ming China and Joseon Korea. His conquest of Ming China's northeastern Liaoning province laid the groundwork for the conquest of the rest of China by his descendants, who founded the Qing dynasty in 1644. He is also generally credited with ordering the creation of a new written script for the Manchu language based on the Mongolian vertical script.
