Jurchen is a term used to collectively describe a number of East Asian Tungusic-speaking people. They lived in northeastern China, also known as Manchuria, before the 18th century. The Jurchens were renamed Manchus in 1635 by Hong Taiji. Different Jurchen groups lived as hunter-gatherers, pastoralist semi-nomads, or sedentary agriculturists. Generally lacking a central authority, and having little communication with each other, many Jurchen groups fell under the influence of neighbouring dynasties, their chiefs paying tribute and holding nominal posts as effectively hereditary commanders of border guards.

Manchu is a critically endangered East Asian Tungusic language native to the historical region of Manchuria in Northeast China. As the traditional native language of the Manchus, it was one of the official languages of the Qing dynasty (1644–1912) of China, although today the vast majority of Manchus speak only Mandarin Chinese. Several thousand can speak Manchu as a second language through governmental primary education or free classes for adults in classrooms or online.
