By participating in the abolitionist movement, women came to think more about their own rights and they gained credibility among some men. This allowed them to form a women's movement.
As women participated in the abolitionist movement, they came to think about the irony of pushing to give African Americans rights that they did not enjoy themselves. This encouraged many to think of their own rights.
Because women had participated forcefully and well in the abolitionist movement, some men were more willing to accept that women might deserve rights. This gave a little more support for the idea of a women's movement.
