The main issue for the U.S. women's suffrage movement was securing the right to vote for women. Spanning the late 19th and early 20th centuries, the movement aimed to challenge legal and societal barriers that denied women equal participation in democracy. Activists like Susan B. Anthony, Elizabeth Cady Stanton, and later Alice Paul and Carrie Chapman Catt played pivotal roles in advocating for suffrage. They organized protests, petitions, and campaigns to raise awareness and garner support. The culmination of their efforts led to the ratification of the 19th Amendment in 1920, granting women the right to vote and symbolizing a significant milestone in the fight for gender equality.
