The Qing Dynasty was the final dynasty of the Chinese Empire, which ruled from 1644 to 1912. The Qing were ethnic Manchus of the Aisin Gioro clan, from the northern Chinese region of Manchuria.
By the early 20th century, the Qing rulers were being undermined by aggressive foreign powers, rural unrest, and military weakness. The Last Emperor, the 6-year-old Puyi, abdicated in February of 1912.
Qing means "bright" or "clear" in Chinese.
"The Qing Dynasty did not pacify all of China until 1683, some nineteen years after they officially took power in Beijing."
