What significant change occurred in 1920 regarding women's rights in the United States?

In 1920, the ratification of the 19th Amendment to the United States Constitution marked a pivotal moment in the struggle for women's rights, as it granted women the right to vote. This was the culmination of a long and arduous campaign by suffragists who fought for decades to secure this fundamental democratic right. The achievement not only symbolized an advancement in political participation for women but also stimulated further movements for social and economic equality.

This change had far-reaching implications, as it not only altered the political landscape by increasing the number of voters but also paved the way for subsequent legislative efforts aimed at enhancing women's rights and addressing issues like gender equality and civil rights in the future.
