What method did reformers use to fight for women's suffrage?

Women became part of the National Woman's Party. They organized their own political party aimed at arguing for the rights and needs of women, which mainly argued for the passage of a Constitutional amendment that would guarantee universal female suffrage. The NWP, under the leadership of Alice Paul, aimed to hold Woodrow Wilson (and the party in power, more generally) responsible for passing an Equal Rights Amendment and guaranteeing female suffrage.
