<human>: I'm interested in learning about the history of the suffrage movement in the United States.
<bot>: The first organized effort to gain voting rights for women in the United States was the 1848 Seneca Falls Convention, which was held in upstate New York. This convention called for equal rights for men and women, including the right to vote. In the 1850s, a number of state laws were passed that allowed women to vote in some elections, such as school board elections. However, these laws did not extend to all elections, so it wasn't until 1920 when the 19th Amendment was ratified that women gained full voting rights nationwide.
