The major event in the early 20th century aimed at securing women’s rights to vote was the women's suffrage movement, culminating in the ratification of the 19th Amendment in 1920. This movement gained momentum throughout the late 19th and early 20th centuries, with activists like Susan B. Anthony and Elizabeth Cady Stanton leading the charge. The push for suffrage was rooted in broader social reform movements and gained traction during and after World War I, as women took on roles traditionally held by men. The victory symbolized a landmark change in gender equality and expanded democratic participation in the United States.
