How were women granted the right to vote in united states

Explanation:

Starting around the 1800s, women started organizing and petitioning to win the right to vote, but it took them decades to accomplish their purpose.

The amendment was  introduced in Congress in 1878, especially because a few years ago the fifteenth amendment took place to give african american men the right to vote.

After a lengthy and difficult struggle, agitation and protest, by the beginning of the mid-19th century, several generations of woman suffrage supporters lectured, wrote, marched and practiced civil disobedience to achieve a resolution. By 1920 finally, the 19th Amendment was introduced to the U.S. Constitution, giving women's  the right to vote.
