Early covenants and deed restrictions were established to control the people who could buy in a development. In the early postwar period after World War II, many were defined to exclude African Americans and, in some cases, Jews, with Asians also excluded on the West Coast. For example, a racial covenant in a Seattle, Washington, neighborhood stated, "No part of said property hereby conveyed shall ever be used or occupied by any Hebrew or by any person of the Ethiopian, Malay or any Asiatic race." In 1948, the United States Supreme Court ruled such covenants unenforceable in "Shelley v. Kraemer". But, private contracts effectively kept them alive until the Fair Housing Act of 1968 prohibited such discrimination.
