# Communism in the 20th Century

History: OCR A GCSE Cold War & International Relations, topic 1.2.2

## Socialism and Communism in the 20th Century

The main communist countries in the 20th century were the Soviet Union, China, Cambodia, Vietnam, and Cuba.

### Famine and socialism in the 20th century

![Famine and socialism in the 20th century](https://image-v2.cdn.app.senecalearning.com/2018-04/c346dcf7-c51a-4d74-8681-32c9bb70a4b3/shutterstock_88472053.jpg)

- Between 1917 and 2017, communist governments presided over the deaths of 100 million of their own citizens. 
- The collectivisation of farming transferred food production and land from individual farmers who owned crops to a government-owned farming project. Once the government controlled all of the country's food, food could be withheld from people to make them do whatever the government wanted. If they didn't comply, they starved to death. Poor organisation, incompetence, or a lack of information could also lead to less deliberate famines.
 - In Stalin's Russia in the 1930s, up to 3.3 million people died in Ukraine in the 'Holodomor' meaning 'extermination by hunger'.
 - In Mao's China, up to 45 million people are thought to have died from starvation and famine.

### Concentration of power and socialism in the 20th century

- In socialism, all economic and political decisions in a society are made centrally. Power is naturally concentrated into the hands of a very small number of people, a bit like a dictatorship.
 - After Stalin succeeded Lenin as the leader of the USSR, the Moscow Trials tried and executed many of Stalin's political rivals - Zinoviev, Kamenev, and Bukharin. 
 - Stalin had a secret police called the NKVD who arrested 1.5 million people, caused the death of 680,000 people and sent 635,000 to gulags in Siberia (forced work camps). The NKVD had quotas for the minimum number of people that they had to arrest. 
 - In Cambodia, a communist party, the Khmer Rouge killed up to 2 million Cambodians, including political rivals and enemies of Pol Pot, the Khmer Rouge leader.

### Incentives and socialism in the 20th century

![Incentives and socialism in the 20th century](https://image-v2.cdn.app.senecalearning.com/memory-location-images/Fenghuang,%20China-min.jpg)

- In socialism, a small number of individuals decide everything that must be produced in a country. An individual is told what to produce and they are not permitted to produce anything else. 
- There is little incentive for workers to work hard, as people gain no additional benefit for working harder or for making higher quality products. 
- Although social planners try to guide control economies, they have the brainpower, innovation and information of only a small number of individuals in government.  
- Since China shifted closer to a capitalist model, companies like Tencent and Alibaba were founded and innovation in China and the standard of living has risen rapidly.
