After the end of WW2 the US feared its wartime ally, China, would become communist. In 1946 after the end of Japanese occupation China returned to a civil war which had been fought on and off for years. America saw China as a future ally in business and politics and sent General George Marshall to broker peace between the nationalists and the communists. But just as the communist leader of the Soviet Union, Joseph Stalin, was advising the Chinese communist leader Mao Zedong to enter into a truce, the British leader Winston Churchill gave his famous speech about an 'iron curtain' descending over Europe and the Cold War began to take hold.

In the first half of the 20th century, most mentally ill patients were locked away in psychiatric hospitals and asylums. Those suffering from severe mental illnesses like schizophrenia, were often sedated or restrained. Shock therapies were standard treatments.
