'Shelley v. Kraemer' was a landmark United States Supreme Court case in 1948 that dealt with racial covenants in property deeds. The case involved the Shelley family, an African-American family who purchased a home in St. Louis, Missouri, that had a racially restrictive covenant which prohibited the sale of the property to African-Americans. When a white family, the Kraemers, sought to enforce the covenant and prevent the Shelleys from moving in, the case went to court.

The Supreme Court ruled in favor of the Shelleys, declaring that state enforcement of racially restrictive covenants violated the Equal Protection Clause of the Fourteenth Amendment. This decision struck a significant blow against the practice of racial segregation in housing and set an important legal precedent for challenging discrimination in housing based on race.

'Shelley v. Kraemer' is significant in Black history as it was a key legal victory in the fight against housing discrimination and segregation. The case paved the way for future civil rights legislation and was a step towards dismantling the systemic racism that pervaded American society at the time.
