What is the most important thing historically about Plessy vs. Ferguson? It did away with Jim Crow laws.
It was the first law suit heard by the court on race issues.
It made Jim Crow Laws legal.
O Plessy was more white than black but was still arrested.
PLEASE HURRY

It made Jim Crows law legal.

This is because it allowed segregation to continue, but said services had to be “equal” (though they really weren’t).

Here are why the other answers are wrong:

Jim Crow laws were removed in the 1950s and 1960s, and this case reinforced segregation.

This was not the first lawsuit heard by the court on race issues. One example of an earlier case is Dred Scott V Sandford.

Plessy was a person of color, and was not more white than black.
