What is the 19th Amendment?

Efforts to make American democracy more inclusive have long focused on that most fundamental of rights, the right to vote. The 19th Amendment to the US Constitution, which states, "The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of sex," brought a uniform policy for women's suffrage to all of the states. Prior to 1920, individual states set their own policies for whether and when women could vote. This very cool interactive timeline from the National Constitution Center illustrates the evolution of women's suffrage in the decades leading up to the 19th Amendment. Some of it may surprise you.
