The 1970s saw a dramatic increase in the success rate of U.S. women's organizations pursuing congressional support of legislation designed to remove barriers to the progress of women in economic, political, and social arenas. While women's organizations, including both older organizations such as the National Federation of Business and Professional Women's Clubs (NFBPWC) and newer organizations such as the National Organization for Women (NOW), had lobbied Congress before 1970, that year saw their first major lobbying success. House passage of the Equal Rights Amendment (ERA) in 1970 was followed in 1972 by full congressional passage of the ERA and Title IX of the Educational Amendments Act (prohibiting sex discrimination in education), the Equal Credit Opportunity Act and the Women's Educational Equity Act in 1974, the Pregnancy Discrimination Act and the (unprecedented) congressional extension of the ratification period for the ERA in 1978, as well as a host of measures prohibiting sex discrimination in federal programs. The legislative success of women's organizations has continued, albeit with some fits and starts, into the 1980s and 1990s with pension equity reform, child support enforcement legislation, child care subsidies, and parental leave legislation as important examples. As documented by numerous scholars, in all these cases women's organizations provided the primary lobbying support for the successful legislation.
