for the national Amendment. Alice Paul organized many working class deputations and even sent over 400 blue collar workers to meet with Wilson. Although seen as highly controversial due to the status difference, this move showed Paul's support for all types of women, not just those of prestigious class. After 1920, the National Woman's Party authored over 600 pieces of legislation fighting for women's equality; over 300 were passed. In addition, the NWP continued to lobby for the passage of the Equal Rights Amendment and under president Sarah Tarleton Colvin, who served in 1933, pressed for equal pay. Scholar Mary K. Trigg has noted, "...the NWP played a central role in the women's rights movement after 1945. It stuck to its laser-like focus on the ERA, doggedly lobbying year in and year out for the amendment's introduction in Congress." In 1997, the NWP ceased to be a lobbying organization. Instead, it turned its focus to education and to preserving its collection of first hand source documents from the women's suffrage movement. The NWP continues to function as an educational organization, maintaining and interpreting the collection left by the work of the historic National Woman's Party. Congress passed the ERA Amendment and many states ratified it, but at the last minute in 1982 it was stopped by a coalition of conservatives led by Phyllis Schlafly and never passed.

Title VII of the Civil Rights Act of 1964 In 1963 Congress passed the Equal Pay Act of 1963, which prohibited wage differentials based on sex. The prohibition on sex discrimination was added by Howard W. Smith, a powerful Virginian Democrat who chaired the House Rules Committee. He was a conservative who strongly opposed civil rights laws for blacks, but voted in support of such laws for white women. Smith's amendment was passed by a teller vote of 168 to 133. Historians debate Smith's motivation—was it a cynical attempt to defeat the bill by someone opposed to both civil rights for blacks and women, or did he support women's rights and was attempting to improve the bill by broadening it to include women? Smith expected that Republicans,
