HOW THE HOLIDAY CAME TO BE

A local week that climbed to a national month.

In 1978 the Education Task Force of the Sonoma County, California, Commission on the Status of Women organized a local Women's History Week, timed around March 8. In 1980 President Jimmy Carter declared the first national Women's History Week, and the newly founded National Women's History Project led a coalition that lobbied Congress. Congress passed annual resolutions beginning in 1981, then designated March as Women's History Month in 1987 under Public Law 100-9. Since 1995 presidents have issued an annual proclamation each March.

INTRO

The month that started as a single week

National Women's History Month did not begin in Washington, and it did not begin as a month. It began in Sonoma County, California, in 1978, as a single week organized by a local task force on the status of women. The group set its celebration around March 8, the date already marked elsewhere as International Women's Day.

The idea spread quickly, but the calendar did not. It took a presidential declaration in 1980, the founding of a national project that lobbied Congress, and a string of annual resolutions through the early 1980s before March finally became a full month, in 1987.

That nine-year climb is the real story of the observance. What is now a fixture of every March, recognized by the Library of Congress and the National Archives, started as a small local effort that had to be carried, one resolution at a time, into federal recognition.

INTRODUCTION

Women's History Week, built around March 8, the date long associated with International Women's Day.

It worked locally, and word traveled. But a good local idea does not become a national observance on its own. Someone has to carry it.

CHAPTER 01

A national project takes up the cause

In 1980, a group in Santa Rosa, California, founded the National Women's History Project. Its co-founders, among them Molly Murphy MacGregor, set out to do for the whole country what Sonoma County had done at home. The project gathered educators and organizations into a coalition and turned its attention to Washington.

That same year, the cause reached the White House. President Jimmy Carter declared the first National Women's History Week, for the week of March 2 through 8, 1980. A local week was now a national one, but only by yearly declaration, and only for a week at a time.

CHAPTER 02

One resolution at a time

Federal recognition came in increments, not in a single act. In 1981, Congress passed its first joint resolution on the subject, Public Law 97-28, designating the week beginning March 7, 1982 as Women's History Week. The resolution was co-sponsored by Senator Orrin Hatch of Utah and Representative Barbara Mikulski of Maryland, a Republican and a Democrat backing the same measure.

For several years the pattern repeated: a fresh resolution each spring, a presidential proclamation, a single week. The National Women's History Project kept petitioning for more.

CHAPTER 03

The week becomes a month

The breakthrough came in 1987. After being petitioned by the National Women's History Project, Congress passed Public Law 100-9, which designated the month of March 1987 as Women's History Month. A week had become a month.

Even then the recognition was not automatic. Congress passed additional resolutions between 1988 and 1994, and only since 1995 have presidents issued an annual proclamation each March without interruption. The project that started the climb is still at work: in 2018 it became the National Women's History Alliance, and it selects the theme that frames each year's observance. ]]>
