The Qing Dynasty was established in 1636 by the Manchus. In 1644 the Chinese capital at Beijing was captured and the Ming Dynasty called on the Manchus for aid. The Manchus took advantage of the opportunity and created their own Dynasty.
For 300 years they were able to keep much of the empire cooperative under their leadership by keeping some Ming polices.
Emperors Kangxi and Qianlong strengthened the empire by expanding it, reducing taxes, and increasing the dynasty's wealth by increasing farming and trade.
Labor-intensive farming kept farmers busy growing enough food to supply their own families and the growing populations in the rest of China. Things such as silks with hand-painted artwork become popular.
Lord McCartney brought British goods to China for trade in 1763. Qing leaders opened their ports to more European influence, while Jesuits spreading Christianity, weakening their control and leading the Chinese to fall to British control in later years.
Internal changes played a major role in the downfall of the Qing dynasty, including: corruption, peasant unrest, ruler incompetence, and population growth which led to food shortages and regular famine.
