Who was Jeanette Pickering Rankin?

Jeanette Pickering Rankin was a significant figure in American history, notably recognized as the first woman to be elected to the United States Congress. Serving from Montana, she was not only a trailblazer in this regard, but she also made her mark by being a staunch pacifist. Her votes against both World War I and World War II highlight her commitment to peace, which was a central tenet of her political philosophy. Rankin's actions and beliefs resonated during a time when women were just beginning to gain political agency in the United States, making her contributions especially noteworthy in the context of women's rights and anti-war movements.

In contrast, the other answer options pertain to other historical figures or moments. For instance, the title of the first woman to serve as a senator belongs to Hattie Caraway, while the first woman to lead a congressional committee was Emma Smith DeVoe. Additionally, the position of the first woman elected governor was held by Nellie Tayloe Ross. These figures, while significant, do not encapsulate Rankin's unique position and accomplishments in American history.
