The Qing dynasty was founded not by Han Chinese, who constitute the majority of the Chinese population, but by the Manchu, descendants of a sedentary farming people known as the Jurchen, a Tungusic people who lived around the region now comprising the Chinese provinces of Jilin and Heilongjiang. The Manchus are sometimes mistaken for a nomadic people, which they were not. Early European writers had used the term "Tartar" indiscriminately for all the peoples of Northern Eurasia but in the 17th century Catholic missionary writings established "Tartar" to refer only to the Manchus and "Tartary" for the lands they ruled.
