The American women's rights movement began in the mid-19th century, advocating for equal rights and opportunities for women. Key issues included suffrage, education, and employment rights. The movement gained momentum with events like the Seneca Falls Convention in 1848, where activists like Elizabeth Cady Stanton and Lucretia Mott called for women's right to vote. Throughout the 20th century, the movement evolved, addressing issues such as reproductive rights and workplace equality. Significant milestones included the passage of the 19th Amendment in 1920, granting women the right to vote, and the formation of organizations like the National Organization for Women in 1966, which continues to advocate for women's rights today.
