Answer: Alabama, Georgia, Louisiana, Maryland, Mississippi, South Carolina, & Virginia
History – Southern states were adamantly opposed to the amendment, however, and seven of them—Alabama, Georgia, Louisiana, Maryland, Mississippi, South Carolina and Virginia—had already rejected it before Tennessee’s vote on August 18, 1920. It was up to Tennessee to tip the scale for woman suffrage.
Tennessee Encyclopedia – “In August 1920 the Tennessee General Assembly ratified the Nineteenth Amendment and handed the ballot to millions of American women. The amendment’s jubilant supporters dubbed Tennessee “the perfect 36” because, as the thirty-sixth of the forty-eight states to approve the amendment, it rounded out the three-fourths majority required to amend the Constitution. The legislature’s historic vote inaugurated a new era for women and for politics and secured Tennessee’s place in the annals of American women’s history.”
