Jim Crow Laws, were passed in Southern states, and forced racial discrimination or segregation against black people. For example, Southern states passed laws that restricted African American's access to public places. Such as, schools, restaurants, hospitals, etc. Signs that said "Whites Only" or "Colored" were posted at entrances and exits, water fountains, waiting rooms, and restrooms. By 1914, every Southern State had passed laws that created two separate societies- one black, one white. Jim Crow laws were based on the theory of white supremacy along with being an reaction to Reconstruction.
