What were laws against black people called?

Laws against Black people, particularly in the United States, were often referred to as "Jim Crow laws." These laws enforced racial segregation and discrimination, particularly in the Southern states, from the late 19th century until the Civil Rights Movement in the 1960s. They were designed to maintain white supremacy and limit the rights and freedoms of Black individuals. Other discriminatory laws, such as the Black Codes, were also implemented in various regions, particularly during the Reconstruction era.
