The event considered the start of the modern feminist movement is the Seneca Falls Convention held in 1848. This gathering, led by figures like Elizabeth Cady Stanton and Lucretia Mott, aimed to address the social, civil, and religious rights of women. The convention produced the Declaration of Sentiments, which outlined grievances and asserted the necessity for women's suffrage and equality. It marked a formal beginning of organized advocacy for women's rights in the United States, influencing future generations and movements for gender equality.
