Throughout American history, the right to vote has expanded to include more citizens. In this blog series, OneV’s Top 20 Moments in American Voting History, we highlight key milestones that shaped our democracy.
This week, we arrive at the final moment in our 20-part journey through the most transformative events in American voting history. Since March 28, One Nation Every Vote (OneV) has shared one moment each week that helped expand the right to vote in the United States. Now, we conclude this series with Moment #1: The ratification of the Nineteenth Amendment in 1920, which granted women the constitutional right to vote. This was a milestone that reshaped the American electorate and signaled a major shift in our democracy.
What Led Up to the Nineteenth Amendment?
The fight for women’s suffrage in the United States began long before 1920. It traces back to the early 19th century, when women were largely excluded from formal political life. The Seneca Falls Convention of 1848 is often cited as the formal beginning of the organized women’s suffrage movement. Convened by women’s rights advocates including Elizabeth Cady Stanton and Lucretia Mott, the convention issued a declaration demanding equal rights for women—including the right to vote.
Over the following decades, women organized, lobbied, marched, and protested. Suffragists formed groups like the National Woman Suffrage Association and the American Woman Suffrage Association, later merging into the National American Woman Suffrage Association. These activists fought at both the state and federal levels, facing fierce opposition and enduring repeated setbacks.
By the early 20th century, the movement had gained significant momentum. Women won the right to vote in several Western states, and suffragists ramped up national pressure. Leaders such as Ida B. Wells, Alice Paul, Carrie Chapman Catt, and Mary Church Terrell helped shift public opinion and force the issue onto the national agenda. In 1917, suffragists began picketing the White House—the first time this tactic was used. Some were arrested and jailed, further galvanizing support.
After years of advocacy, sacrifice, and struggle, the U.S. Congress passed the Nineteenth Amendment in 1919. It was ratified by the required number of states on August 18, 1920, and certified on August 26, 1920.
The text was simple, but powerful: “The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of sex.”
What Happened After the Amendment?
The ratification of the Nineteenth Amendment enfranchised millions of women across the country. It marked one of the largest expansions of the electorate in American history. Women began participating in elections at all levels of government, reshaping public policy, shifting political dynamics, and changing the face of American democracy.
However, just like the Fifteenth Amendment, the Nineteenth did not automatically guarantee equal voting rights for all women. Women of color, particularly Black, Native American, Asian American, and Latina women, continued to face voter suppression tactics such as literacy tests, poll taxes, intimidation, and discriminatory laws.
For example, many Native American women were not granted U.S. citizenship—and thus the right to vote—until the Indian Citizenship Act of 1924. It took the Voting Rights Act of 1965 and later legal reforms to address some of the systemic barriers that continued to suppress the votes of women of color.
Why Was This Moment Important?
The Nineteenth Amendment stands as a landmark achievement in the long struggle for equal rights in America. It expanded the promise of democracy to half the population and redefined what it meant to be a citizen in the United States.
This moment also demonstrated the power of collective action. It was the result of decades of organizing, coalition-building, persistence, and courage. The women’s suffrage movement was not a monolith—it was a broad and diverse coalition of voices, many of which are still being rediscovered and recognized today. This amendment helped pave the way for continued advocacy for gender equality in all areas of public life.
Today, women are the majority of registered voters in the United States, and they play a decisive role in every election. But the work is far from over. We continue to face challenges to voting access, particularly for communities that have historically been marginalized.
In 2025, the Nineteenth Amendment reminds us of what is possible when people organize, advocate, and act. It is a call to honor the sacrifices of those who came before us by using the rights they fought so hard to win. The struggle for full, inclusive democracy continues—and every vote counts.
