[Q]: Its knowledge and uses spread from China through the Middle East to medieval Europe in the 13th century, where the first water powered paper mills were built. Because of paper's introduction to the West through the city of Baghdad, it was first called bagdatikos. In the 19th century, industrial manufacture greatly lowered its cost, enabling mass exchange of information and contributing to significant cultural shifts. In 1844, the Canadian inventor Charles Fenerty and the German F. G. Keller independently developed processes for pulping wood fibres.

[Q]: The Qing dynasty was founded not by Han Chinese, who constitute the majority of the Chinese population, but by 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. What was to become the Manchu state was founded by Nurhaci, the chieftain of a minor Jurchen tribe – the Aisin Gioro – in Jianzhou in the early 17th century. Originally a vassal of the Ming emperors, Nurhachi embarked on an intertribal feud in 1582 that escalated into a campaign to unify the nearby tribes. By 1616, he had sufficiently consolidated Jianzhou so as to be able to proclaim himself Khan of the Great Jin in reference to the previous Jurchen dynasty.
