Hard to believe, but it's true. Here's the story:
Matilda Joslyn Gage
Gage became involved in the women's rights movement in 1852 when she decided to speak at the National Women's Rights Convention in Syracuse, New York. She served as president of the National Woman Suffrage Association from 1875 to 1876, and served as either Chair of the Executive Committee or Vice President for over twenty years. During the 1876 convention, she successfully argued against a group of police who claimed the association was holding an illegal assembly. They left without pressing charges.
Gage was considered to be more radical than either Susan B. Anthony or Elizabeth Cady Stanton (with whom she wrote History of Woman Suffrage). Along with Stanton, she was a vocal critic of the Christian Church, which put her at odds with conservative suffragists such as Frances Willard and the Woman's Christian Temperance Union. Rather than arguing that women deserved the vote because their feminine morality would then properly influence legislation (as the WCTU did), she argued that they deserved suffrage as a 'natural right'.
Gage was well-educated and a prolific writer—the most gifted and educated woman of her age, claimed her devoted son-in-law, L. Frank Baum.
--"Indian Citizenship," page 2
By Sally Roesch Wagner
During the 1870s, Gage wrote a series of controversial articles decrying the brutal and unjust treatment American Indians had received. Having already broken numerous treaties, the government was trying to force citizenship upon Native Americans, she argued, thus destroying their independent nation status, and further opening "wide the door to the grasping avarice of the white man." Gage, who was adopted into the wolf clan of the Mohawk nation and given the name Ka-ron-ien-ha-wi (Sky Carrier), wrote of the superior form of government practiced by the Six Nation Iroquois Confederacy, in which "the power between the sexes was nearly equal." This indigenous practice of woman's rights became her vision.
Gage never fragmented her beliefs about changing the world. To her, all freedoms hung together on the same thread and the struggle for them could not be separated. Still, there was one goal that became her life's work and that was the struggle for the complete liberation of women.
Maud Gage Baum
Maud's two sisters and brother were in the Dakota Territory. Because Maud wanted to be near them, she insisted over Frank's vacillations that they move there. Maud, Frank, and her two sons moved to Aberdeen, South Dakota, on September 20, 1888, because Frank believed there would be better business opportunities in the West. Frank started a dry goods store, Baum's Bazaar, on October 1, 1888, to make a stable living for his family. However, because he granted too much credit to his destitute customers, his store went out of business.
The family moved to Chicago, and Frank found a job as a newspaper reporter.
Maud's mother Matilda frequently spent the winter at their house, as she did when Maud and Frank were residents of Aberneen. Maud cherished her mother's visits, especially when Frank traveled for his job.
So Baum was devoted to Gage the Native rights activist. She stayed with him and Maud during the Aberdeen winters.
This was when he wrote two virulently anti-Indian editorials for the Aberdeen Saturday Pioneer. I wonder what they said to each other the day after the editorials appeared.
