What were jim crow laws?

legislation that prevented blacks from voting

legislation meant to integrate blacks and whites

legislation guaranteeing employment rights of blacks and whites

Legislation meant to segregate blacks and whites in a legal way.

As the US supreme court asked that as long as the blacks and white had equal fundings and that all conditions were the same, segregation can be seen as legal. However, this rarely happened, and it led to desegregation by force at the end. The Jim Crow Laws was the birth of this ruling, as it imposed "equal" but segregated laws (such as segregated laws for public transport, bathrooms, resteraunts, etc.) in much of the states.
