Besides the curious early case of New Jersey, women in Utah Territory were the first in the U.S. to cast ballots legally, having won voting rights in early 1870. (A Wyoming Territory law had extended the franchise to approximately 1,500 white women in December 1869, but Utahns actually voted first, in Salt Lake City’s municipal elections in February 1870.) Half a century before the ratification of the Nineteenth Amendment in 1920, as scholar Katherine Kitterman writes, Utah was home to the “first substantial population of voting women in the United States.” Yet the pioneering history of women’s suffrage in Utah has been obscured by controversies over Mormon polygamy: “Polygamy was the precipitating factor for Utah’s 1870 suffrage law, and it was the reason Congress revoked Utah women’s voting rights in 1887.”
