Civil Rights Movement
From 1966 to 1968, the civil rights movement focused a lot on fair housing. Even outside the South, fair housing was a problem. For example, in 1963, California passed a Fair Housing Act which made segregation in housing illegal. White voters and real estate lobbyists got the law reversed the next year. This helped cause the Watts Riots. (Later, in 1966, California made the Fair Housing Act the law again.)
