The Texas Equal Suffrage Association (TESA) was an organization founded in 1903 to support white women's suffrage in Texas. It was originally formed under the name of the Texas Woman Suffrage Association (TWSA) and later renamed in 1916. TESA did allow men to join. TESA did not allow black women as members, because at the time to do so would have been "political suicide." The El Paso Colored Woman's Club applied for TESA membership in 1918, but the issue was deflected and ended up going nowhere. TESA focused most of their efforts on securing the passage of the federal amendment for women's right to vote. The organization also became the state chapter of the National American Woman Suffrage Association (NAWSA). After women earned the right to vote, TESA reformed as the Texas League of Women Voters.

Jane Yelvington McCallum was an American politician and author, a women's suffrage and Prohibition activist, and the longest-serving Secretary of State of Texas. She attended schools in Wilson County, Texas, for the most part, and studied at the University of Texas at Austin for several years. As a suffragist, she published many columns in local newspapers in support of that cause and others. She was a member of numerous organizations. In 1927, she campaigned for Dan Moody and would be appointed as the Secretary of State after his successful election as governor. After leaving the position in 1933, she remained active in writing, activism, and political and civic affairs until she died in 1957.
