On this day in history, February 27th 1922, the 19th Amendment to the U.S. Constitution, providing for female suffrage, is unanimously declared constitutional by the eight members of the U.S. Supreme Court. The 19th Amendment, which stated that “the right of citizens of the United States to vote shall not be denied or abridged by the United States or any State on account of sex,” was the product of over seven decades of meetings, petitions, and protests by women suffragists and their supporters.
