Imagine having to sit at the back of the bus, just because of your skin color. Less than 100 years ago, it was common in the United States to block African Americans from job opportunities, stores, and restaurants that were only for white people. They were also banned from many public services and forced to use lower quality public toilets, hospitals, and even schools. Sitting in the front of a public bus was just one form of legal discrimination that African Americans faced at that time.
