Women's History Month grew out of a weeklong commemoration by Jimmy Carter in 1980

Years before it became a full month, there was Women’s History Week.

In 1978, Sonoma County, Calif., held the first known Women’s History Week to align with International Women’s Day.

At the time, women’s history was “virtually an unknown topic in the K-12 curriculum or in general public consciousness,” according to the National Women’s History Alliance.
