'Shelly v. Kraemer' was a landmark U.S. Supreme Court case that dealt with racial discrimination in housing. The case was brought before the Supreme Court in 1948 and involved the enforcement of racially restrictive covenants, which were clauses included in property deeds that prohibited the sale of the property to individuals of certain races.

In the case, the Shelley family, a Black family, purchased a home in St. Louis, Missouri, which was subject to a racially restrictive covenant. The previous owners, the Kraemers, sued to enforce the covenant and prevent the Shelleys from taking possession of the property.

The Supreme Court ruled in favor of the Shelleys, stating that while the enforcement of private agreements such as restrictive covenants was not unconstitutional, state courts could not enforce them as they violated the Equal Protection Clause of the Fourteenth Amendment.

The 'Shelley v. Kraemer' decision was significant as it marked a legal milestone in the fight against housing discrimination and segregation. While restrictive covenants continued to be used in some places, the case paved the way for later fair housing legislation and further efforts to combat racial discrimination in housing.
