The Civil Rights Act of 1964 was the most sweeping civil rights legislation of its day, and included women's rights as part of its reforms. Ironically, the section on women's rights was added by a senator from Virginia who opposed the whole thing and was said to be sure that if he stuck something about womens' rights into it, it would never pass. The bill passed anyway, though, much to the chagrin of a certain wiener from Virginia.
