The main focus of the women's rights movement in the early 20th century was achieving suffrage, or the right to vote. Activists fought against societal norms that restricted women's roles and sought legal recognition of women's rights. Key events included the Seneca Falls Convention in 1848 and the formation of organizations like the National American Woman Suffrage Association. By employing strategies such as protests, campaigns, and lobbying, these activists worked tirelessly to challenge the legal frameworks that denied women the vote. Their efforts culminated in the passage of the 19th Amendment in 1920, granting women the legal right to vote in the United States.
