On July 16, 1848, in another home owned by Richard Hunt (known as the M’Clintock House in the upstate New York village of Waterloo), Elizabeth Cady Stanton, with the help of her colleagues, drafted a "Declaration of Sentiments."
That document served as a rallying cry for the first Women’s Rights Convention which began three days later in the Wesleyan Chapel of Seneca Falls (this is a PDF link). Three hundred women and men, including the abolitionist Frederick Douglass, attended.
The Declaration of Sentiments, largely patterned after the Declaration of Independence, declares that women, as well as men, are created equal:
We hold these truths to be self-evident; that all men and women are created equal; that they are endowed by their Creator with certain inalienable rights; that among these are life, liberty, and the pursuit of happiness; that to secure these rights governments are instituted, deriving their just powers from the consent of the governed.
The continuing problem for American women, of course, was that they were governed without their consent.
