National Women’s History Month dates back to March 8, 1857, when women from New York City factories staged a protest over working conditions.
International Women’s Day was first observed in 1909, but it wasn’t until 1981 that Congress established National Women’s History Week to be commemorated the second week of March.
In 1987, Congress expanded the week to a month. Every year since, Congress has passed a resolution for Women’s History Month, and the President has issued a proclamation.
The U.S. Census Bureau collected statistics related to the month.
