Final answer:
The aftermath of Buck v Bell in Europe influenced the development of compulsory sterilization laws in Europe, such as the Law for the Prevention of Offspring with Hereditary Diseases in Germany in 1933.
Step-by-step explanation:
The aftermath of Buck v Bell in Europe was not immediate as the case specifically pertained to the United States. However, it did have an influence on the development of compulsory sterilization laws in Europe. The case upheld the right of state governments to sterilize individuals believed likely to have children who would become dependent upon public welfare. This decision, coupled with the eugenics movement in the United States, influenced European countries such as Germany to enact similar laws, such as the Law for the Prevention of Offspring with Hereditary Diseases in 1933 which allowed for the sterilization of 'unfit' parents and potential parents.
