The main goal of the suffragette movement in the early 20th century was to secure voting rights for women in the United States. Activists argued that women deserved equal political representation and rights, advocating for suffrage through protests, rallies, and lobbying efforts. Figures like Susan B. Anthony and Elizabeth Cady Stanton were instrumental in organizing these efforts, emphasizing the importance of women's voices in political matters. Their tireless work culminated in the passing of the 19th Amendment in 1920, granting women the right to vote and representing a significant victory for gender equality and civil rights.
