Texas women won the right to vote in primary elections in 1918, two years before the 19th Amendment to the U.S. Constitution was ratified. In January 1919, an amendment to the state constitution enfranchising women finally passed through the legislature but was defeated at the ballot box by male voters in May of that year. Women were still barred from voting in that general election. The following month, after decades of arguments across the country, Congress passed the federal women’s suffrage amendment on June 4, 1919. On June 28, 1919, the Texas legislature voted to ratify the 19th Amendment – the first Southern state to do so. By August 18th 1920, 36 states (including Texas) approved the amendment and it became part of the United States Constitution.
