This is a timeline of women's suffrage in Iowa. Women's suffrage work started early in Iowa's history. Organizing began in the late 1960s with the first state suffrage convention taking place in 1870. In the 1890s, women gained the right to vote on municipal bonds, tax efforts and school-related issues. By 1916, a state suffrage amendment went to out to a voter referendum, which unfortunately failed. Iowa was the tenth state to ratify the Nineteenth Amendment in 1919.
