The Nineteenth Amendment was certified and incorporated into the U.S. Constitution by Secretary of State Colby.
On August 26, 1920, the Nineteenth Amendment was officially certified by Secretary of State Bainbridge Colby. This certification process legally incorporated the amendment into the U.S. Constitution, making its guarantee against sex-based disfranchisement fully operative nationwide. This event was a formal validation of years of advocacy and activism. It also marked a pivotal moment where women could participate as equal citizens in the governance of their country. The certification ceremony was notably understated, lacking any public fanfare, yet its impact would reverberate through generations.
