Answer:
It made racial segregation legal in the United States.
Explanation:
A shoemaker of New Orleans, Homer Plessy, purchased a rail ticket On June 7, 1892, and sat in a train reserved for people from the white race. The State Law of Louisiana allowed separate railway cars for African Americans and Caucasians. The case, which concluded with a landmark decision of the Supreme Court Plessy v. Ferguson, decided that the policy of "separate but equal" was legitimate and that states could enact legislation requiring racial segregation. This case has established segregation practices popular in public buildings, including trains, theaters, hotels, restaurants, washrooms, and public toilets.
