The significant change brought about by the 19th Amendment for women in the United States was the establishment of their right to vote. Ratified in 1920, this amendment marked a monumental victory for the women's suffrage movement, which had been advocating for women's voting rights for decades. This legal change empowered women to participate in the electoral process and engage more actively in political life. It catalyzed further advancements in women's rights, prompting discussions about equality and representation, and it laid the groundwork for subsequent movements aimed at achieving broader gender equality in various spheres of society.
