Jill Derr answers that she believes it was, at least in part, a result of Emeline's life: Emeline was married at 15, a mother at 16 and deserted by her husband, later married two more times, and during her life had to support herself. You can understand why Emeline was a supporter of women's rights and suffrage because she saw that women needed the ability to care for themselves when life gave them lemons.
After that part in the program, the commentators talked about how women in Utah had the vote in 1870, lost it when the government felt Utah had too much voting power, then received it again in 1896 when Utah became a state. They suggest that it was easily acceptable for women to have the vote in early Utah because women naturally voted in church affairs, so why shouldn't they in civic?
Women in early Utah are so fascinating to me. They had a different culture than the rest of the United Sates; they were quite liberated in many ways. I'd continue to like to learn more about:
- how did women's rights affect the women in Utah
- how did Utah women influence women's rights, and who
- how much did polygamy enable women to participate more in the community and politics
