Plessy vs Ferguson ruling established the practice of

Answer 1

"separate but equal" segregation, allowing for the legal segregation of public facilities based on race. This ruling upheld the constitutionality of laws mandating racial segregation in public facilities such as schools, buses, and train cars as long as the facilities were deemed to be equal in quality. This decision laid the foundation for decades of systemic racism and discrimination in the United States, until it was eventually overturned by the landmark Supreme Court case Brown v. Board of Education in 1954.
