Nineteenth Amendment to the United States Constitution [SEP] Introduction
The Nineteenth Amendment (Amendment XIX) to the United States Constitution prohibits the states and the federal government from denying the right to vote to citizens of the United States on the basis of sex. Initially introduced to Congress in 1878, several attempts to pass a women's suffrage amendment failed until passing the House of Representatives on May 21, 1919, followed by the Senate on June 4, 1919. It was then submitted to the states for ratification. On August 18, 1920, Tennessee was the last of the necessary 36 ratifying states to secure adoption. The Nineteenth Amendment's adoption was certified on August 26, 1920: the culmination of a decades-long movement for women's suffrage at both state and national levels.
