Wich best describe the jim crow laws?

Southern States passing laws that enforced discrimination against African Americans.

Jim Crow laws were laws created by white southerners to enforce racial segregation across the South from the 1870s through the 1960s.

Under the Jim Crow system, "whites only" and "colored" signs proliferated across the South at water fountains, restrooms, bus waiting areas, movie theaters, swimming pools, and public schools. African Americans who dared to challenge segregation faced arrest or violent reprisal.

In 1896, the Supreme Court declared Jim Crow segregation legal in the Plessy v. Ferguson decision. The Court ruled that "separate but equal" accommodations African Americans were permitted under the Constitution.
