June 4, 1919–August 18, 1920

Congress passes the 19th Amendment on June 4, 1919, declaring that “the right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of sex.” However, three-fourths of US states—or 36 out of 48—must ratify the amendment before it can be validated. On August 18, 2020, Tennessee becomes the 36th ratifying state, validating the amendment.
