Answer:
Homer Plessy
Step-by-step explanation:
In 1892, Homer Plessy deliberately violated the Separate Car Act by sitting in a "whites-only" railroad car.
The Separate Car Act of 1890 was a Louisiana law that mandated racial segregation on trains, requiring separate accommodations for African Americans and whites.
Plessy's act of civil disobedience led to the famous legal case Plessy v. Ferguson, which reached the United States Supreme Court in 1896. The Supreme Court's decision in this case upheld the constitutionality of racial segregation under the "separate but equal" doctrine, which allowed segregation as long as the facilities provided to different racial groups were deemed equal. This decision had significant and long-lasting implications for the legal status of segregation in the United States until it was overturned by the Brown v. Board of Education decision in 1954.
