This month pays tribute to the generations of women whose commitment to nature and the planet have proved invaluable to society. The celebration was met with positive response, and schools began to host their own Women's History Week programs. The next year, leaders from the California group share their project at a Women's History Institute at Sarah Lawrence College. Other participants not only became determined to begin their own local Women's History Week projects but also agreed to support an effort to have Congress declare a national Women's History Week.
In 1981, Sen. Oran Hatch (R-UT) and Rep. Barbara Mikulski (D-MD) cosponsored the first Joint Congressional Resolution proclaiming a "Women's History Week." In 1987, the National Women's History Project petitioned Congress to expand the celebration to the entire month of March. Since then, the National Women's History Month Resolution has been approved every year with bipartisan support in both the House and Senate.
