Economy of the Qing dynasty
The Qing dynasty (1644–1912) was the most populated country on Earth for nearly two centuries and had a large and varied economy. The High Qing era saw a period of rapid demographic and economic growth, followed by a near century of stagnation brought about by the unequal treaties, rebellions, floods, and a fiscally conservative and decentralised government.
