In Qing China a series of changes occurred that weakened its power and ultimately lead to its downfall. This included corruption and ruler incompetence, population growth and peasant unrest. Also there were food shortages and widespread famine.  

Explanation:

Although the imperial system in China had lasted more than 2,000 years,  Chinese imperial power came to an end under the Qing dynasty in 1911-1912. There were a series of conflicts such as the Boxer Rebellion of 1899–1901 and Wuchang Uprising of 1911–1912 that also led to the regime's demise. Qing rule gradually collapsed during the second half of the 19th century due to a complicated interplay between internal and external factors including population growth that arose with technological advances in agriculture.  By 1900 foreign countries like Britain and Germany had "spheres of influence" developing along China's coastal areas which further weakened the Qing Dynasty's position.
