ANSWER -
The following events took place in China during the 20th century:
Boxer Rebellion (1899-1901)
Chinese Civil War (1927-1949)
Mao Zedong takes power (1949)
The Great Leap Forward (1958-1962)
Cultural Revolution (1966-1976)
The causes of the Great Leap Forward are not limited to one specific event, but rather a combination of factors including Mao Zedong's ideas, the desire to modernize and industrialize the country, and political and economic conditions in China at the time. Some historians argue that the failure of earlier modernization efforts and the desire to catch up with the developed world may have also been contributing factors.
