Who were the prominent leaders of the women's rights movement that began in the 1840s?

The prominent leaders of the women's rights movement that began in the 1840s were Elizabeth Cady Stanton and Susan B. Anthony. They were pivotal figures in the fight for women's suffrage and equality. Stanton is well-known for her role in organizing the Seneca Falls Convention in 1848, where the declaration asserting women's rights was established. She emphasized the importance of women's involvement in political processes.

Susan B. Anthony collaborated closely with Stanton, dedicating her life to the cause of women's rights and advocating for women's suffrage through organizational efforts and public speaking. Together, they founded the National Woman Suffrage Association, which played a significant role in the movement advocating for legislative changes. Their partnership symbolized the broader societal shift towards recognizing women's rights during this period and laid the groundwork for future advancements in gender equality.
