The Republican Party pioneered the right of women to vote and was consistent in its support throughout the long campaign for acceptance. It was the first major party to advocate equal rights for women and the principle of equal pay for equal work.
The Women's Rights Convention held in Seneca Falls, N.Y., in 1848 marked the beginning of the women’s suffrage movement in the United States. Two years later there was a nationwide meeting in Worcester, Mass.
By 1870, the Massachusetts Republican State Convention had already seated two suffragettes, Lucy Stone and Mary A. Livermore, as delegates. In addition, the National Republican Convention of 1872 approved a resolution favoring the admission of women to “wider fields of usefulness” and added that “the honest demand of this class of citizens for additional rights ... should be treated with respectful consideration.”
