Answer:
Plessy v. Ferguson
Explanation:
<u> Plessy v. Ferguson's landmark case happened in 1896. when African American Homer Plessey refused to sit in a separate car for black people.</u> The laws that proclaimed these racial segregations were called Jim Crow laws. The came comes from the parody of black people, song<em> Jump Jim Crow</em>. It enforced racial separation of the public space, so African American people couldn’t be mixed with white people.<u> We can see on the photo that protestor is declaring “Jim Crow must go” which means the racial laws must be revoked.</u>
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.
