Heart of Atlanta v. United States (1964) - Any business that was participating in interstate commerce would be required to follow all rules of the federal civil rights legislation. In this case, a motel that wanted to continue segregation was denied because they did business with people from other states. This important case represented an immediate challenge to the Civil Rights Act of 1964, the landmark piece of civil rights legislation which represented the first comprehensive act by Congress on civil rights and race relations since the Civil Rights Act of 1875.

However, black Americans ' fight for equal civil rights was far from over. In particular, the southern United States, where the Heart of Atlanta Motel was located, remained segregated even into the late 1960s.Passed on July 2, 1964, the Civil Rights Act of 1964 banned racial discrimination in public places, particularly in public accommodations, largely based on Congress ' control of interstate commerce.The Heart of Atlanta motel was a large, 216-room motel in Atlanta, Georgia, which refused to rent rooms to black patrons, in direct…
