This 1943 newspaper advertisement urged Americans to write their congressman and demand the repeal of Chinese Exclusion. World War II put new pressure on the Chinese Exclusion Act. Advocates pointed to the contradiction of going to war to protect freedom, while discriminating against immigrants from an allied nation.
Proponents of repeal, like the China Daily News, asked Chinese Americans to testify before Congress and challenge discrimination. Non-Chinese supporters founded the Citizens Committee to Repeal Chinese Exclusion, which included Pearl Buck, best-selling author of The Good Earth. President Roosevelt signed repeal into law in December 1943.
