Answer:
Plessy v. Ferguson
Step-by-step explanation:
Plessy v. Ferguson's landmark case happened in 1896. when African American Homer Plessey refused to sit in a separate car for black people. The laws that proclaimed these racial segregations were called Jim Crow laws. The came comes from the parody of black people, song Jump Jim Crow. It enforced racial separation of the public space, so African American people couldn’t be mixed with white people. We can see on the photo that protestor is declaring “Jim Crow must go” which means the racial laws must be revoked.
The case changed the laws to the “separate but equal” doctrine, which declared that facilities and spaces for all races must be equal in quality.
