Final answer:
Plessy v. Ferguson upheld the separate but equal doctrine, which justified the implementation of Jim Crow laws that enforced racial segregation and discrimination.
Step-by-step explanation:
The Supreme Court case of Plessy v. Ferguson had a significant effect on Jim Crow laws. In this case, the Supreme Court upheld the separate but equal doctrine, which allowed for the segregation of White and Black people in public places. Therefore, Plessy v. Ferguson provided legal justification for the implementation of Jim Crow laws, which enforced racial segregation and discrimination in various aspects of life, such as schools, transportation, and public facilities.
As a result of the Plessy vs Ferguson decision, Jim Crow laws were enacted throughout the Southern states. These laws enforced segregation in various aspects of daily life, including public facilities, schools, housing, and voting rights. African Americans were subjected to systemic discrimination, denied equal opportunities, and faced racial violence and intimidation.
