Plessy v. Ferguson- basically Louisiana passed a law saying the black people need it separate car when traveling on train not on the same as a white person.
Plessy was 1/8 African descent (was born free and other 7/8 was of European descent ) and under Louisiana rule he had to sit on a black car. eventually he sat on white only car and got into trouble, just like Rosa Parks. and he was eventually got arrested and tried.
Bc they didn't want anymore colonies to build up
