The Civil Rights Act of 1964 (42 U.S. C.A.) (the 19 Act) likely has had the greatest transformative effect on American society of any single law. By prohibiting discrimination based on race, color, sex, religion, a national origin in places of public accommodation, in federally assisted programs, in employment, in schools and with respect to voting rights, this massive law has had profound effects on almost every facet of American society.
