As the first national law to address racial discrimination in housing, the 1968 Fair Housing Act was truly a landmark piece of legislation. It prohibited homeowners, real-estate agents, lenders, and other housing professionals from engaging in a range of practices they had commonly used to keep neighborhoods racially segregated, such as refusing to sell or rent to a person because of his or her race, lying about the availability of a dwelling, or blockbusting (inducing white owners to sell by telling them that blacks were moving into the neighborhood). The last of the 1960s-era civil rights laws, the Fair Housing Act tackled the arena long felt to be the most sensitive to whites. Intense controversy, demonstrations, and violence over fair housing issues had occurred in many cities and states since at least the 1940s. Although John F. Kennedy promised during his presidential campaign to end housing discrimination “with the stroke of a pen,” once elected, he waited two years to sign a limited executive order. In 1966, a fair housing bill supported by President Johnson failed in Congress. Unlike other civil rights bills, the issue of housing evoked opposition not just from the South but also from the North. Opponents claimed that it challenged basic American values such as “a man's home is his castle”; to supporters, the symbolism of homeownership as “the American Dream” only underscored the importance of ensuring that housing was available to all Americans, regardless of race.
