The Mothers' Movement refers to the coalition of 20th century left wing groups and organizations in the United States predominantly made up of female members. They represented an anti-World War II, anti-Communist, anti-Roosevelt, anti-Semitic and pro-Nazi agenda. Their numbers included:
- National Legion of Mothers of America (formed by Father Charles Coughlin in 1939)
- National Blue Star Mothers
- Crusading Mothers of America
- We, the Mothers
- We, the Mothers, Mobilize for America
With a membership of up to 6 million, they wielded considerable influence, and were only halted by the Great Sedition Trial in 1944.
The Mothers' Movement began in California in 1939, shortly after the German invasion of Poland. It grew rapidly until around 100 separate groups were affiliated to it, with estimates of at least 6 million members, although the Chicago Tribune, which championed their cause, claimed that there were 10 million members alone in just one group, the National Legion of Mothers of America.
