Suffrage Map, 1919
This map shows which states allowed women to vote before the 19th Amendment. Suffragists used such maps to track their progress and to persuade states that were reluctant to give women the vote. Note how the map depicts the various levels of suffrage women had, and how, from state to state, it differed.
