Racial segregation enforced the separation of blacks and whites in public facilities through Jim Crow laws, which claimed to create "separate but equal" treatment but did not in reality. Examples of segregation included separate drinking fountains, restaurants that prohibited people of color, and Rosa Parks challenging segregation on buses. Over time, figures like Martin Luther King Jr. led protests and demonstrations against segregation, advocating for full racial equality. While segregation caused harm, photographs show that its end has allowed for an integrated society with a black president.
