The significance of August 18

On August 18, 1920, Secretary of State Bainbridge Colby certified the 19th Amendment, giving American women the constitutional right to vote. The amendment had been before Congress in some form since 1878. The decisive moment came two days earlier in the Tennessee legislature: 24-year-old Harry Burn changed his vote from “no” to “yes” after reading a letter from his mother Phoebe, who wrote: “Don’t forget to be a good boy and help Mrs. Catt put the ‘Rat’ in ratification.” That letter, now in the Tennessee State Library, swung the amendment. The Catholic Church celebrates the feast of St. Helena on August 18. Helena, mother of Emperor Constantine, reportedly discovered the True Cross in Jerusalem around 326 AD.
