Since women were not allowed in politics or public institutions, they started organizing into pressure groups which would sign petitions or publish books and political pamphlets or would organize marches or similar activities whose goal was to fight for equality. They would use these ways to promote things such as general suffrage or other ideas.
They broadened the notion of freedom because they started fighting against slavery and joined abolitionist groups. They explained how slaves and women were subjugated by men and how it needed to change and they got many people to become abolitionists as well because it was considered that the people were not equal until the African-Americans were enslaved and women were forbidden from voting.
