The 19th Amendment was a key step for women's rights in the U.S.

It included just 28 words, but a single sentence transformed the civil rights of women in the United States. It was Article I of the 19th Amendment to the U.S. Constitution, and it guaranteed that “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.” Passed by Congress on June 4, 1919 and made into law in August 1920, the amendment gave women political power over 130 years after the nation’s founding.

It was the culmination of a century of agitation for women’s suffrage. Beginning in the 1840s, women organized in a concerted effort to gain the vote. Their goal seemed almost impossible: In 1848, when suffragist Elizabeth Cady Stanton organized the first convention for women’s rights in Seneca Falls, New York, the right to vote was just one in a litany of rights barred to women. They were discouraged from appearing or speaking in public. Their lives were controlled by those of their husbands, brothers, and fathers, and most women could not sign contracts, work outside the home, inherit or own property, or receive an education.

Nonetheless, women across the United States organized and fought for the right to vote. “There never will be complete equality until women themselves help to make laws and elect lawmakers,” wrote suffragist Susan B. Anthony. Her sentiment was shared by generations of suffragists.

Women's long fight for the vote

It was a difficult fight. Some suffragists voted illegally and served time in prison. Others chained themselves to the gates of the White House and refused to work once they got to jail. Still others used acts of nonviolent and even violent civil disobedience.

Their first successes were in the West, where some male legislators hoped giving women the right to vote might attract more women to territories like Wyoming, Colorado, and Utah. However, these early victories did not consist of men handing the vote to women; rather, they were long fought.

Though local suffrage slowly opened to women in many states, suffragists continued their fight for national voting rights through the 19th century. Mocked, jailed, beaten, and force-fed, they defied the era’s stereotypes of female propriety.

During the early 20th century, suffragists focused their efforts on a constitutional amendment. Using tactics like massive parades and a years-long picket at the White House, they slowly bent public opinion toward voting rights for women. A suffrage amendment was first introduced in 1878; it took 41 years for Congress to send it to the states for ratification.

Looking ahead for women's rights

The 19th Amendment opened up political influence to women, but not all shared in suffrage for some time. Black women were often barred from polls through much of the 20th century; Native American and Asian American women faced citizenship bars for many years. 

(For Black women, the 19th Amendment didn’t end their fight to vote.)

Nor did the amendment guarantee equal rights; a proposed amendment guaranteeing women equal protection under the Constitution has yet to become law, and women still face significant societal disparities compared to men. In April 2023, a measure to extend the ratification deadline failed in the Senate. Fifty-one senators approved extending the deadline, but the measure needed 60 votes to go into effect. 

Though women are outnumbered in public office three to one and the U.S. has yet to elect a woman president, women vote in greater numbers than men.
