The women of Idaho gained the right to vote in 1896 along with women in Utah that same year. Only in the Territory of Wyoming and the State of Colorado did women earn the right to vote previously, in 1869 and 1893 respectively. In comparison, national suffrage did not become a reality until the ratification of the 19th Amendment on August 18, 1920.
