On this day in 1919, Congress approved the woman’s suffrage amendment and sent it to the states for ratification. Adding the amendment to the Constitution required ratification by three-fourths of the states, which at that time was 36 of 48.
The National Woman’s Party led by Alice Paul began sewing stars on a giant purple, white, and gold flag. Each time a state ratified the 19th Amendment, a new star would be sewn on the flag.
The 19th Amendment became law more than a year after Congress approved the amendment. The 36th state, Tennessee, voted to ratify on August 18, 1920. This image shows Alice Paul unfurling that flag from the suffrage headquarters on that day.
The Library of Congress is home to the NWP records and library collection.
