Step-by-step explanation:
Jim Crow laws restricted African Americans from having basic human rights. This is what started segregation in the United States back in the 1900s. Because of those laws, black people and white people needed to be & stay separated because black people were, and still are, seen as "unworthy", "dirty", and "insuperior" compared to white people. Black and white people had their own designated places where each were allowed while the other wasn't. For example, their were bathrooms for only white people and bathrooms for only black people. This was also for schools, resturants, public places, etc.
