The Great Leap Forward was an industrialization campaign within China from 1958 to 1962, led by the Chinese Communist Party (CCP). CCP Chairman Mao Zedong launched the campaign to transform the country from an agrarian society into an industrialized society through the formation of people's communes. The Great Leap Forward is estimated to have led to between 15 and 55 million deaths in mainland China during the 1959–1961 Great Chinese Famine it caused, making it the largest or second-largest famine in human history.
The Great Leap Forward stemmed from multiple factors, including "the purge of intellectuals, the surge of less-educated radicals, the need to find new ways to generate domestic capital, rising enthusiasm about the potential results mass mobilization might produce, and reaction against the sociopolitical results of the Soviet Union's development strategy." Mao ambitiously sought an increase in rural grain production and an increase in industrial activity. Mao was dismissive of technical experts and basic economic principles, which meant that industrialization of the countryside would solely be dependent on the peasants. Grain quotas were introduced with the idea of having peasants provide grains for themselves and support urban areas. Output from the industrial activities such as steel was also supposed to be used for urban growth. Local officials were fearful of the Anti-Right Deviation Struggle and they competed to fulfill or over-fulfill quotas which were based on Mao's exaggerated claims, collecting non-existent "surpluses" and leaving farmers to starve to death. Higher officials did not dare to report the economic disaster which was being caused by these policies, and national officials, blaming bad weather for the decline in food output, took little or no action.
